returning different values from the enter and leave functions, the\n * behavior of the visitor can be altered, including skipping over a sub-tree of\n * the AST (by returning false), editing the AST by returning a value or null\n * to remove the value, or to stop the whole traversal by returning BREAK.\n *\n * When using visit() to edit an AST, the original AST will not be modified, and\n * a new version of the AST with the changes applied will be returned from the\n * visit function.\n *\n * const editedAST = visit(ast, {\n * enter(node, key, parent, path, ancestors) {\n * // @return\n * // undefined: no action\n * // false: skip visiting this node\n * // visitor.BREAK: stop visiting altogether\n * // null: delete this node\n * // any value: replace this node with the returned value\n *

Kind: {\n * enter(node) {\n * // enter the \"Kind\" node\n * }\n * leave(node) {\n * // leave the \"Kind\" node\n * }\n * }\n * })\n *\n * 3) Generic visitors that trigger upon entering and leaving any node.\n *\n * visit(ast, {\n * enter(node) {\n * // enter any node\n * },\n * leave(node) {\n * // leave any node\n * }\n * })\n *\n * 4) Parallel visitors for entering and leaving nodes of a

After this only fields \"between\" sets are compared.\n *\n * B) Also, if any fragment is referenced in a selection set, then a\n * comparison is made \"between\" the original set of fields and the\n * referenced fragment.\n *\n * C) Also, if multiple fragments are referenced, then comparisons\n * are made \"between\" each referenced fragment.\n *\n * D) When comparing \"between\" a set of fields and a referenced fragment, first\n * a comparison is made between each field in the original set of fields and\n * each field in the the referenced set of fields.\n *\n * E) Also, if any fragment is referenced in the referenced selection set,\n * then a comparison is made \"between\" the original set of fields and the\n * referenced fragment (recursively referring to step D).\n *\n * F) When comparing \"between\" two fragments, first a comparison is made between\n * each field in the first referenced set of fields and each field in the the\n * second referenced set of fields.\n *\n * G) Also, any fragments referenced by the first must be compared to the\n * second, and any fragments referenced by the second must be compared to the\n * first (recursively referring to step F).\n *\n * H) When comparing two fields, if both have selection sets, then a comparison\n * is made \"between\" both selection sets, first comparing the set of fields in\n * the first selection set with the set of fields in the second.\n *\n * I) Also, if any fragment is referenced in either selection set, then a\n * comparison is made \"between\" the other set of fields and the\n * referenced fragment.\n *\n * J) Also, if two fragments are referenced in both selection sets, then a\n * comparison is made \"between\" the two fragments.\n *\n */\n// Find all conflicts found \"within\" a selection set, including those found\n// via spreading in fragments.

However, when Apollo iOS sends queries to the server, it does so without any line breaks using Swift's `.appending()` method. Then when the server calculates the SHA, due to the lack of line breaks, the operation ID is different and the error is thrown. Strangely enough, however, I noticed the StarWars API actually [manually adds line breaks](https://github.com/apollographql/apollo-ios/blob/06c357b7e98fb7abcddc02ca8aeb96cc8475d263/Sources/StarWarsAPI/API.swift#L1051) in its generated code, which mine doesn't. \r\n\r\nI believe I'm using the latest version of Apollo Codegen and Apollo iOS. I'm happy to patch a fix – it's just a matter of what needs to be changed.

You can see the code changes in-place in [this PR](https://github.com/apollographql/apollo-ios/pull/1341). I will be updating this RFC with feedback as it is received. \r\n\r\n## Why The Change?\r\n\r\n`HTTPNetworkTransport` allows you to hook into various delegates to accomplish various things. There are several limitations to this approach: \r\n\r\n- Users can only do things that are specifically supported by delegates.\r\n- Asynchronous use of delegates without callbacks is basically impossible.\r\n- Any time we want to add a new feature, we need to add a new delegate method and handle it, creating additional complexity.\r\n- There is no flexibility in terms of order of operations, particularly around whether data should be returned to the UI before being written to the cache.\r\n\r\nThe other major issue driving this update is that the current networking stack is *deeply* tied to the current cache architecture. This isn't ideal for many reasons, the biggest of which is that the cache likely to change in relation to the [Swift Codegen Rewrite](https://github.com/apollographql/apollo-ios/issues/939). \r\n\r\n## What is proposed? \r\n\r\nThe proposed new architecture uses the Interceptor pattern to create a customizable request chain. This means users can hook into the system at any point during the request creation or data processing process. \r\n\r\nThis also means that the pieces which will need to be swapped out for the Swift Codegen Rewrite are more clearly defined, and less tied to the actual parsing operation. \r\n\r\nFinally, this also opens the opportunity for different patterns than we already support, such as writing to the cache *after* returning data to the UI instead of before, or creating an array of interceptors which hit the network first, then hit the cache if nothing was returned. \r\n\r\n### New Protocols\r\n\r\n- **`FlexibleDecoder`**: This is mostly going to be helpful for the `Codable` implementation down the line, but this will allow anything conforming to `Decoder` to be used to decode data.\r\n- **`Parseable`**: This is a wrapper that allows us to continue to support non-`Codable` parsing alongside `Codable` parsing, while keeping us able to constrain and construct things generically. A default implementation for `Codable` will be provided.\r\n- **`ApolloInterceptor`**: This is an interface which allows you to add an asynchronous handler to perform any necessary work, such as fetching credentials and reading or writing from the cache, asynchronously. \r\n \r\n ```swift\r\n public protocol ApolloInterceptor: class {\r\n \r\n /// Called when this interceptor should do its work.\r\n ///\r\n /// - Parameters:\r\n /// - chain: The chain the interceptor is a part of.\r\n /// - request: The request, as far as it has been constructed\r\n /// - response: [optional] The response, if received\r\n /// - completion: The completion block to fire when data needs to be returned to the UI.\r\n func interceptAsync(\r\n chain: RequestChain,\r\n request: HTTPRequest,\r\n response: HTTPResponse?,\r\n completion: @escaping (Result, Error>) -> Void)\r\n }\r\n ```\r\n \r\n Default implementations of `ApolloInterceptor` for both Legacy (ie, non Swift Codegen) networking and Swift Codegen networking will be provided.\r\n- **`InterceptorProvider`** This protocol will be used to quickly create a new array of interceptors for a given request:\r\n\r\n ```swift\r\n public protocol InterceptorProvider {\r\n \r\n /// Creates a new array of interceptors when called\r\n ///\r\n /// - Parameter operation: The operation to provide interceptors for\r\n func interceptors(for operation: Operation) -> [ApolloInterceptor]\r\n }\r\n ```\r\n This design allows for both flexibility (you can return different interceptors for different types of requests, for instance) and isolation (each request will have its own unique set of interceptors, reducing the possibility of different requests stomping on each other). \r\n \r\n Two default interceptor providers are set up: \r\n - **`LegacyInterceptorProvider`** will provide interceptors mimicking the current stack \r\n - **`CodableInterceptorProvider`** will provide interceptors for the forthcoming Swift Codegen Rewrite's network stack. \r\n- **`ApolloErrorInterceptor`** will allow you to have additional checks whenever an error is about to be returned. This will be optional to implement, and no default implementation is provided.\r\n\r\n ```swift\r\n /// Asynchronously handles the receipt of an error at any point in the chain.\r\n ///\r\n /// - Parameters:\r\n /// - error: The received error\r\n /// - chain: The chain the error was received on\r\n /// - request: The request, as far as it was constructed\r\n /// - response: [optional] The response, if received\r\n /// - completion: The completion closure to fire when the operation has completed. Note that if you call `retry` on the chain, you will not want to call the completion block in this method.\r\n func handleErrorAsync(\r\n error: Error,\r\n chain: RequestChain,\r\n request: HTTPRequest,\r\n response: HTTPResponse?,\r\n completion: @escaping (Result, Error>) -> Void)\r\n ```\r\n \r\n### New Classes\r\n\r\n- **`HTTPRequest`** This object will hold all the information related to a request before it hits the network, with the `toURLRequest()` method creating an actual `URLRequest` based on all the information in the request. This is subclass-able (and will mostly be using subclasses). \r\n\r\n ```swift\r\n open class HTTPRequest {\r\n\r\n open var graphQLEndpoint: URL\r\n open var operation: Operation\r\n open var contentType: String\r\n open var additionalHeaders: [String: String]\r\n open var clientName: String? = nil\r\n open var clientVersion: String? = nil\r\n open var retryCount: Int = 0\r\n public let cachePolicy: CachePolicy\r\n\r\n public init(graphQLEndpoint: URL,\r\n operation: Operation,\r\n contentType: String,\r\n additionalHeaders: [String: String],\r\n cachePolicy: CachePolicy = .default)\r\n \r\n open func toURLRequest() throws -> URLRequest\r\n\r\n open func addHeader(name: String, value: String)\r\n }\r\n ```\r\n \r\n - **`JSONRequest`** subclass of `HTTPRequest` will handle creating requests with JSON, which will be the vast majority of requests with operations. This is where handling of auto-persisted queries is also layered in: \r\n\r\n ```swift\r\n public class JSONRequest: HTTPRequest {\r\n \r\n public let requestCreator: RequestCreator\r\n \r\n public let autoPersistQueries: Bool\r\n public let useGETForQueries: Bool\r\n public let useGETForPersistedQueryRetry: Bool\r\n public var isPersistedQueryRetry = false\r\n \r\n public let serializationFormat = JSONSerializationFormat.self\r\n\r\n public init(operation: Operation,\r\n graphQLEndpoint: URL,\r\n additionalHeaders: [String: String] = [:],\r\n cachePolicy: CachePolicy = .default,\r\n autoPersistQueries: Bool = false,\r\n useGETForQueries: Bool = false,\r\n useGETForPersistedQueryRetry: Bool = false,\r\n requestCreator: RequestCreator = ApolloRequestCreator())\r\n }\r\n ```\r\n \r\n - **`UploadRequest`** subclass of `HTTPRequest` will handle multipart file uploads:\r\n\r\n ```swift\r\n public class UploadRequest: HTTPRequest {\r\n \r\n public let requestCreator: RequestCreator\r\n public let files: [GraphQLFile]\r\n public let manualBoundary: String? \r\n public let serializationFormat = JSONSerializationFormat.self\r\n \r\n public init(graphQLEndpoint: URL,\r\n operation: Operation,\r\n additionalHeaders: [String: String] = [:],\r\n files: [GraphQLFile],\r\n manualBoundary: String? = nil,\r\n requestCreator: RequestCreator = ApolloRequestCreator()) \r\n }\r\n ```\r\n\r\n- **`HTTPResponse`** will represent the objects returned and/or parsed from the server:\r\n\r\n ```swift\r\n /// Designated initializer\r\n ///\r\n /// - Parameters:\r\n /// - response: The `HTTPURLResponse` received from the server.\r\n /// - rawData: The raw, unparsed data received from the server.\r\n /// - parsedResponse: [optional] The response parsed into the `ParsedValue` type. Will be nil if not yet parsed, or if parsing failed.\r\n public class HTTPResponse {\r\n public var httpResponse: HTTPURLResponse\r\n public var rawData: Data\r\n public var parsedResponse: GraphQLResult?\r\n }\r\n ```\r\n\r\n- **‌`RequestChain`** will handle the interaction with the network for a single operation. \r\n\r\n ```swift\r\n public class RequestChain: Cancellable {\r\n\r\n /// Creates a chain with the given interceptor array\r\n public init(interceptors: [ApolloInterceptor])\r\n \r\n /// Kicks off the request from the beginning of the interceptor array.\r\n ///\r\n /// - Parameters:\r\n /// - request: The request to send.\r\n /// - completion: The completion closure to call when the request has completed.\r\n public func kickoff(\r\n request: HTTPRequest, \r\n completion: @escaping (Result) -> Void)\r\n \r\n /// Proceeds to the next interceptor in the array.\r\n /// \r\n /// - Parameters:\r\n /// - request: The in-progress request object\r\n /// - response: [optional] The in-progress response object, if received yet\r\n /// - completion: The completion closure to call when data has been processed and should be returned to the UI.\r\n public func proceedAsync(\r\n request: HTTPRequest, \r\n response: HTTPResponse?,\r\n completion: @escaping (Result) -> Void)\r\n \r\n /// Cancels the entire chain of interceptors.\r\n public func cancel()\r\n \r\n /// Restarts the request starting from the first inteceptor.\r\n ///\r\n /// - Parameters:\r\n /// - request: The request to retry\r\n /// - completion: The completion closure to call when the request has completed.\r\n public func retry(\r\n request: HTTPRequest,\r\n completion: @escaping (Result) -> Void)\r\n }\r\n ```\r\n- **`RequestChainNetworkTransport`** provides an implementation of `NetworkTransport` which uses an `InterceptorProvider` to create a request chain for each request. \r\n ```swift\r\n public class RequestChainNetworkTransport: NetworkTransport {\r\n \r\n public init(interceptorProvider: InterceptorProvider,\r\n endpointURL: URL,\r\n additionalHeaders: [String: String] = [:],\r\n autoPersistQueries: Bool = false,\r\n cachePolicy: CachePolicy = .default,\r\n requestCreator: RequestCreator = ApolloRequestCreator(),\r\n useGETForQueries: Bool = false,\r\n useGETForPersistedQueryRetry: Bool = false)\r\n }\r\n ```\r\n\r\n### Changes to existing Protocols and Classes\r\n\r\n- **`ApolloStore`** will no longer require a `GraphQLQuery` explicitly for fetching data from the store. It will instead return an error if the `GraphQLOperationType` is not `.query`. This change is necessary to avoid going down an enormous rabbit hole with generics since `GraphQLOperation` has an associated type. \r\n- The **`NetworkTransport`** protocol will get a new method to be implemented: \r\n\r\n ```swift\r\n func sendForResult(operation: Operation,\r\n completionHandler: @escaping (Result, Error>) -> Void) -> Cancellable\r\n ```\r\n \r\n This will avoid the double-wrapping of `GraphQLResponse` around the `GraphQLResult` so that only the `GraphQLResult` is actually returned. The `send` method will eventually be deprecated and removed. \r\n- **`ApolloClient`** will get a new `sendForResult` method which calls into the `sendForResult` method added to `NetworkTransport`.\r\n\r\n## How will this work in practice? \r\n\r\nInstantiating a new legacy client manually will look like this: \r\n\r\n```swift\r\nlazy var legacyClient: ApolloClient = {\r\n let url = URL(string: \"http://localhost:8080/graphql\")!\r\n \r\n let store = ApolloStore(cache: InMemoryNormalizedCache())\r\n let provider = LegacyInterceptorProvider(store: store)\r\n let transport = RequestChainNetworkTransport(interceptorProvider: provider, endpointURL: url)\r\n \r\n return ApolloClient(networkTransport: transport)\r\n}()\r\n```\r\n\r\nIdeally I'll be able to transparently swap out the existing `HTTPNetworkTransport` for this so that this would be the under-the-hood setup on `ApolloClient`, but this may involve a transition period. \r\n\r\nCalls to the client will look like this: \r\n\r\n```swift\r\nlegacyClient.fetchForResult(query: HeroNameQuery()) { result in\r\n switch result {\r\n case .success(let graphQLResult):\r\n print(graphQLResult.data?.hero?.name ?? \"Name not found\")\r\n case .failure(let error):\r\n print(\"Unexpected error: \\(error)\")\r\n }\r\n}\r\n```\r\n\r\nNote that this is VERY similar to how they look on the surface at the moment, which is intentional. \r\n","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"Overall this looks great.

Can you clarify for me?\r\n\r\nBasically, we have the `GraphQLOperation` protocol, with an associated type of `Data`, and its three sub-protocols, `GraphQLQuery`, `GraphQLMutation`, and `GraphQLSubscription`. Previously, we were limiting what operations could read from the cache to `GraphQLQuery`, since in theory that's the only place getting something from the cache would matter. \r\n\r\n`HTTPRequest` only requires a specification of `GraphQLOperation`, but when making a call into the cache, we can't use the `Blah is GraphQLQuery` method of figuring out whether a `GraphQLOperation` is a query because of the `associatedType` on `GraphQLOperation`. \r\n\r\nI tried about 15 different workarounds for this and this is the only one that wasn't monstrously over-complicated - everything else involved some mild-to-completely bizarre type erasure strategies. I'm not totally against those, but I think in this case the benefits of going that way were vastly outweighed just changing the gating of this a bit.","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"and if you have specific feedback on #1341 I'd love to hear it - just be aware that there's definitely a lot that's WIP (thus the TODOs)","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"OK, I've done some poking around on the request for a typed error parameter, and I don't think it's going to be doable at the interceptor level.\r\n\r\nWhen I tried to add this in, any existing `Error` I tried to return would cause a \"Cannot convert value\" build failure: \r\n\"Screen\r\n\"Screen\r\n\r\nIt'd make the interceptors a lot harder to keep independent if they all had to have exactly the same type of error. It also wouldn't be possible for me to have default implementations return errors without having `TypedError` conform to some other protocol that allows me to return an underlying arbitrary error. Ultimately, I think that adds too much complexity for general use cases.\r\n\r\nI think if you want to write your own typed wrapper that takes whatever's returned and feeds it into something with an `underlying` error that's easier to switch on, that could work. But I think requiring everything have to be the same type at a protocol level is going to lead to a hell of a lot more confusion than it solves. \r\n\r\nWould love to hear feedback on this finding.","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"One of the things that's nice about the `ApolloLink` abstraction used for the web version of Apollo Client is that the link chain is more like a linked list, rather than an array, with each link deciding how to forward the request on to the rest of the chain (and how to process the response), without needing an overarching `RequestChain` to manage the list of links.\r\n\r\nConcretely, this kind of approach would probably mean the `InterceptorProvider` would return a single `ApolloInterceptor` (analogous to `ApolloLink`), representing the head of the linked list, rather than a `[ApolloInterceptor]` array. The last interceptor in the chain (the tail of the list) would be responsible for performing the actual HTTP request, in most cases—but not always!\r\n\r\nSometimes you want to terminate the chain with something that makes an HTTP request, but other times the terminal link might provide its own data (for example, mock data during tests). Sometimes you might want to split a request between multiple downstream links, or choose among several servers that can handle different kinds of requests (or load-balance the same type of request between multiple servers, entirely on the client). It's hard to represent branching structures like that as an array, because it's no longer really a list, but a dynamic tree. But if each interceptor gets to make its own decisions about how it passes requests to the rest of the chain (and how it handles the responses), the branching can be hidden as an implementation detail, with each interceptor abstracting over everything downstream from it.\r\n\r\nI don't know enough Swift to anticipate specific ways in which this approach might be tricky, but it seems like it should be possible to give the interceptor chain more of a recursive, potentially tree-like structure. That's worked pretty well on the web, in the sense that I haven't had to worry very much about the `ApolloLink` system, even as I've changed large portions of the rest of the library.\r\n\r\nFor reference, here's an overview of `ApolloLink` concepts that I've found useful in the past: https://www.apollographql.com/docs/link/overview/","author":{"__typename":"User","login":"benjamn","id":"MDQ6VXNlcjU3NTA=","name":"Ben Newman"}},{"__typename":"IssueComment","body":"I think one huge, huge difference is that things like cancellation, retry, and thread management can be handled through javascript's `Observable` reactive system. \r\n\r\nThat just isn't doable without either using Combine (which would require dropping everything below iOS 12, and is unfortunately a non-starter with a number of our larger users) or adding some kind of Reactive library as a dependency (which I am loathe to do because of the *massive* number of dependency conflicts it could introduce). \r\n\r\nHowever, I think you're right that splitting out methods for request setup vs response handling is a good idea - this could at least help reduce the number of things that need to be optional on `HTTPResponse`. \r\n\r\nWill futz with this tomorrow.

From the perspective of links earlier in the chain, a request that succeeded after several retries looks exactly like one that succeeded on the first try, except that it might have taken a bit longer. If retrying was something you could implement in a perfectly generic way for all interceptors, it might make sense to hoist it to a higher layer of the system (maybe into `RequestChain`), but in practice retrying tends to be sensitive to application concerns (different logic for different queries, even), so I think it makes sense to push it down into a part of the system that can be customized by application developers.\r\n\r\nI think we can agree it's important for interceptors to be able to perform any kind of async work as an implementation detail, which requires a uniformly asynchronous API. Both `Observable` and Combine provide that kind of API, but they are both probably overkill, or at the very least they would need to earn their way into a system like this. I believe you that Combine is not worth it for iOS, but then again I'm not sure `Observable` is totally defensible for JS applications, either.","author":{"__typename":"User","login":"benjamn","id":"MDQ6VXNlcjU3NTA=","name":"Ben Newman"}},{"__typename":"IssueComment","body":"> When I tried to add this in, any existing `Error` I tried to return would cause a \"Cannot convert value\" build failure:\r\n\r\nfrom this error it looks like you changed the signature of `handleErrorAsync` to:\r\n```swift\r\nfunc handleErrorAsync(\r\n error: TypedError,\r\n chain: RequestChain,\r\n request: HTTPRequest,\r\n response: HTTPResponse,\r\n completion: @escaping (Result) -> Void)\r\n```\r\n\r\nwhile I was thinking something like: \r\n```swift\r\nfunc handleErrorAsync(\r\n error: Error, // keep this one untyped so that you can pass anything you need\r\n chain: RequestChain,\r\n request: HTTPRequest,\r\n response: HTTPResponse,\r\n completion: @escaping (Result) -> Void) // but allow users to wrap the internal errors in their own custom types\r\n```\r\nso that you can give a default implementation that does not wrap the error type: \r\n```swift \r\nextension ApolloErrorInterceptor where TypedError == Error {\r\n// default interceptor with a untyped completionHandler\r\n```\r\n\r\nsorry I wasn't clear with the previous message.

This itself is based on [`OkHttp` library's `Interceptor` type](https://square.github.io/okhttp/interceptors/) that's used very widely throughout the Android ecosystem for networking.\r\n\r\nIn `OkHttp`, there's a chain that takes an array of interceptors. Each interceptor in the array needs to call `proceed` before it can keep going, and then each one calls `intercept` to handle the result.

That said, it is the only conclusion that survived our tests. Having found this https://stackoverflow.com/questions/62612056/why-dispatchqueue-global-still-alive-after-deinit on StackOverflow, we think that the problem stems from the queue keeping alive the instance of the `URLSession` created in `URLSessionClient` in some fashion.\r\n\r\nThis causes multiple retains climbing up the dependence graph of:\r\n- URLSession\r\n- URLSessionClient\r\n- HTTPNetworkTransport\r\n- ApolloClient\r\n- Objects in our code that calls ApolloClient ...\r\n\r\n### OUR SOLUTION\r\nAdding the following to `HTTPNetworkTransport` fixes both our issues:\r\n```\r\ndeinit {\r\n self.client.session.invalidateAndCancel()\r\n}\r\n```\r\n\r\nWe understand that this is most probably not the solution you will want to implement but it might help as a starting point to formulate something that will not jeopardize others that use your framework.\r\n\r\n### OUR INVESTIGATION\r\nIt should be said that we took the liberty to try this as there was code in the `URLSessionClient` for `deinit` that clears all tasks. We surmised that clearing the tasks in that situation did not cause a problem for calls in progress, meaning that clients of the framework should not expect the calls to complete if they stop holding their instance of `ApolloClient`.\r\n\r\nBut we noticed that the `deinit` in the `URLSessionClient` was never called even when its parent `HTTPNetworkTransport` `deinit` was called. We then noticed that the `HTTPNetworkTransport` was never deallocated even though its `deinit` was called.\r\n\r\nThat made us realize that something further down the line was probably holding things recursively. Implementing our solution, everything gets deallocated and for some reason, further ApolloClients return their calls successfully.\r\n\r\n### CONCLUSION\r\nAdvice on how to go forward from here would be greatly appreciated.\r\nThanks in advance for your help. We stand ready to answer any of your questions should you have some.","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"Hi!

So in my app I'm having a list of conversations, so I'm creating a `watch` on a query that returns the list of conversations, this is something like that:\r\n\r\n```\r\nuser {\r\n uuid\r\n firstName\r\n lastName\r\n conversations {\r\n uuid\r\n unreadMessagesCount\r\n }\r\n}\r\n```\r\n\r\n> In the app we use the `uuid` key to handle cache, so we make sure to always pass `uuid` in our queries to automatically handle cache update.\r\n\r\nSo the role of the watcher I'm talking about is both to update existing conversations and also be able to catch when a new conversation is created (it can happen and not be initiated by the user, we then trigger an event from the backend that is listen from a subscription in the app). When this event happens it returns something like that\r\n\r\n```\r\nevent {\r\n newConversation {\r\n conversation {\r\n uuid\r\n unreadMessagesCount\r\n // This is the part that adds the new conversation to the existing ones of the users in the cache\r\n user {\r\n uuid\r\n conversations {\r\n uuid\r\n unreadMessagesCount\r\n }\r\n } \r\n }\r\n }\r\n}\r\n```\r\n\r\nIt works great, meaning that when this event happens, the watcher is being called with the newly created conversation, but the issue is that any new cache update for that specific conversation doesn't trigger the watcher again.\r\n\r\nAfter investigating a bit, I realised that the cache is being updated because if I'm adding 3 new messages into the new conversation (setting the `unreadMessagesCount` to 3), the watcher doesn't get called but then if I add 1 new message into an old one, the watcher is being called with both the new message on the old conversation and the 3 new on the new one. \r\n\r\nSo it really seems like `watch` is not being called again for changes on an item that wasn't in a collection when the `watch` was initially made. I've also take a look at https://github.com/apollographql/apollo-ios/issues/281 and making a `fetch` on the same query again after the event doesn't fix the issue.\r\n\r\nLet me know if I'm not clear on something as the whole thing is a bit complicated to explain.","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"Hi!

Apologize for noise.)_\r\n\r\n# Problem\r\n\r\nWe have done some experiments in adopting pagination and encountered a few issues. I am looking for a recommendation on how to extract paginated results that do achieve two of my main goals. For the context, we have a mobile application that has screens that show paginated content that allows infinite vertical scrolling.\r\n\r\n1. Perform pagination in a responsible manner without any lag on the UI\r\n2. Ability to watch any changes to the items retrieved across all pages\r\n\r\nFor example, assume the following schema\r\n\r\n```\r\ntype PageResult {\r\n cursor: String\r\n hasMore: Bool\r\n items: [String]\r\n}\r\nquery {\r\n getItems(cursor: String): PageResult\r\n}\r\n```\r\n\r\nHere are the approaches we tried:\r\n\r\n## Approach 1: Follow the suggestion as per the [Apollo iOS tutorial blog](https://www.apollographql.com/docs/ios/tutorial/tutorial-pagination/)\r\n\r\n1. Load the first page with no cursor with cache policy that writes data back to the cache\r\n2. Load the second page with the cursor and follow the same for the next pages with cache policy that writes data back to the cache\r\n\r\n### Issues with Approach 1\r\n\r\n#### 1. Zombie records:\r\n\r\nFollowing the query path approach to generate cache key, the First page will be written under cache key \"QUERY\\_ROOT.getPage-cursor\", while subsequent pages will hold the items under the cache key \"QUERY\\_ROOT.getItems-cursor-page2cursor\", \"QUERY\\_ROOT.getItems-cursor-page3cursor\", and so on..\r\n\r\nIn our case, The page cursors are generated run time and only valid until the first page is refreshed again to get a new cursor. Following this approach, We notice that all the pages that were previously fetched will never be deleted after re-fetching the first page and hence get accumulated as the user fetches more pages and re-fetches leading to larger cache size over time. Not to mention the more number of records, the higher the read time.\r\n\r\n#### 2. Cannot watch updates to items from the second page onwards:\r\n\r\nWe want to set up a GraphQLQueryWatcher on the paginated query, such that any changes to the items, including items from all the pages retrieved so far. However, Looking at the implementation of the GraphQLQueryWatcher, it appears that with this approach, Watcher will notify only for the items returned from the first page since dependent keys for the watcher includes only keys from the first page.\r\n\r\n## Approach 2: Manually merge data from subsequent pages into the first page\r\n\r\nIn order to solve the Approach #1 Issue #2, We took inspiration from [Apollo react Pagination](https://www.apollographql.com/docs/react/data/pagination/#cursor-based) which does the following:\r\n\r\n1. Load the first page with no cursor with cache policy that writes data back to the cache\r\n2. Load the second page, and so on, with `fetchIgnoringCacheCompletely` cache policy and manually write the data into the First-page query.\r\n\r\n### Issues with Approach 2\r\n\r\n#### 1. Writes are slow\r\n\r\nAs we can notice in Step #2, we merge the previous page with data pulled from the next page and re-write the entire data back. As we fetch more pages, the write latency increases.\r\n\r\n#### 2 Latency of reading the first page exponentially increases\r\n\r\nSince we merge data from all pages into the first page, reading the first page exponentially increases based on the number of items present in the cache. This is more evident with queries that have an increasing number of attributes that are non-scalar data types in the query as the batch loader does round trip to the database for each attribute. With our sample of data, the read time for a query with medium complex schema has clocked 10 seconds to read 150 items on an iPhone XS device.","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"Hey @bharath2020 - just a heads up that I'm bogged down at the moment but this is a *very* good question that I need to work on a better answer to (and that we should have a *way* better answer to overall for mobile), and I think messing around with the tutorial is probably a good place to start with it. And you are very correct that 10 seconds to read 150 items is 🤮. \r\n\r\nIn terms of what you can try while I'm digging out from under what I'm dealing with now, there's the `cacheKeyForObject` closure that you can use to generate a custom cache key. For most items you should be able to cache by ID, and that should avoid having to rewrite all the data if it's not necessary. \r\n\r\nI'm going to leave this open for the community to respond more - I know this has been done well, but my knowledge of details isn't there because I'm focused on other parts of the SDK at the moment. \r\n","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"Thanks, @designatednerd for the response.\r\n\r\n> For most items you should be able to cache by ID, and that should avoid having to rewrite all the data if it's not necessary.\r\n\r\nInteresting. In approach #2, Given that I am appending items from `morePage` back to `firstPage` and issuing a re-write of data for the first-page query, I am curious how would the store understand to not overwrite data referencing items in the first page? In other words, I understand `cacheKeyForObject` would reduce the number of records written to the database, but even with normalized cache, there would be unnecessary overwrites (in this case the items in the first page) that would add to the write latency. Please correct me If I am wrong.\r\n\r\nP.S. I have cacheKeyForObject enabled in my sample, and timings were taken after. The only part where I would not be able to generate a cache key is for the `PageResult` type, as `cacheKeyForObject` does not expose the variables (or field arguments) used to generate the type, in this case, it is the `cursor` provided for `getItems(cursor:)` query.","author":{"__typename":"User","login":"bharath2020","id":"MDQ6VXNlcjkwMzUzNg==","name":null}},{"__typename":"IssueComment","body":"Again, my knowledge of the cache is not as deep as it should be, but my understanding is you'd be rewriting the references with IDs rather than the entire object and its entire tree of changes. This almost certainly has some unnecessary work, but it would likely constitute a lot *less* unnecessary work than without the `cacheKeyForObject`. \r\n\r\nAnd again, this is not working as well as we want it to. We have some changes to the cache slated for [phases 2 and 3 of the ongoing Swift codegen rewrite](https://github.com/apollographql/apollo-ios/issues/939), and making things less annoying for pagination is one of the major things I want to do within that work. \r\n\r\nWish I had a better answer for you.

When this event happens it returns something like that\r\n\r\n```\r\nevent {\r\n newConversation {\r\n conversation {\r\n uuid\r\n unreadMessagesCount\r\n // This is the part that adds the new conversation to the existing ones of the users in the cache\r\n user {\r\n uuid\r\n conversations {\r\n uuid\r\n unreadMessagesCount\r\n }\r\n } \r\n }\r\n }\r\n}\r\n```\r\n\r\nIt works great, meaning that when this event happens, the watcher is being called with the newly created conversation, but the issue is that any new cache update for that specific conversation doesn't trigger the watcher again.\r\n\r\nAfter investigating a bit, I realised that the cache is being updated because if I'm adding 3 new messages into the new conversation (setting the `unreadMessagesCount` to 3), the watcher doesn't get called but then if I add 1 new message into an old one, the watcher is being called with both the new message on the old conversation and the 3 new on the new one. \r\n\r\nSo it really seems like `watch` is not being called again for changes on an item that wasn't in a collection when the `watch` was initially made. I've also take a look at https://github.com/apollographql/apollo-ios/issues/281 and making a `fetch` on the same query again after the event doesn't fix the issue.\r\n\r\nLet me know if I'm not clear on something as the whole thing is a bit complicated to explain.","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"To add more to this, I feel like this is not related to collections only.

Also, I may just be missing things!\r\n\r\nThere are two ways to set up an `ApolloStore` for the networking in Apollo, and unless both are done, in the same way, I believe there can be inconsistencies.\r\n\r\nFor example, we previously did this in our `ApolloClient` setup:\r\n\r\n```swift\r\nlet networkTransport = HTTPNetworkTransport(url: baseURL)\r\nlet cache = InMemoryNormalizedCache()\r\nlet store = ApolloStore(cache: cache)\r\nlet client = ApolloClient(networkTransport: networkTransport, store: store)\r\n```\r\n\r\nWhen upgrading to the newest version of Apollo, we originally re-wrote this as:\r\n\r\n```swift\r\nlet provider = LegacyInterceptorProvider()\r\nlet networkTransport = RequestChainNetworkTransport(interceptorProvider: provider, endpointURL: baseURL)\r\nlet cache = InMemoryNormalizedCache()\r\nlet store = ApolloStore(cache: cache)\r\nlet client = ApolloClient(networkTransport: networkTransport, store: store)\r\n```\r\n\r\nAs far as I can tell (please tell me if I'm wrong!) this has set up a store that is now not being used at all. We can still call `client.clearCache()` or `client.cacheKeyForObject` and it will use the store that we created, but this would _not_ affect the store being used by the interceptors.\r\n\r\nSimilarly, we could have configured a more complex cache setup, but that would not be used by the interceptors.\r\n\r\nIf we corrected this in the following way...\r\n\r\n```swift\r\nlet cache = InMemoryNormalizedCache()\r\nlet store = ApolloStore(cache: cache)\r\nlet provider = LegacyInterceptorProvider(store: store)\r\nlet networkTransport = RequestChainNetworkTransport(interceptorProvider: provider, endpointURL: baseURL)\r\nlet client = ApolloClient(networkTransport: networkTransport)\r\n```\r\n\r\n...this would also introduce bugs because while our correct store is being used for the networking, `client.clearCache` or `client.cacheKeyForObject` are pointing to the `ApolloClient`'s default store from its init method.\r\n\r\n## Versions\r\n\r\n- `apollo-ios` SDK version: 0.34.1\r\n- Xcode version: 12.0\r\n- Swift version: 5.3\r\n\r\n## Steps to reproduce\r\n\r\nSee above for the process that can lead to incorrect use. This is roughly the steps that we took while upgrading Apollo to 0.34.x – i.e. we went through two invalid implementations before reaching one that we believe is valid.\r\n\r\n## Further details\r\n\r\nAs mentioned above, this isn't really a bug, but I think it's a design issue that could be improved. My recommendation would be to eliminate the store from the `ApolloClient` entirely, and leave it up to the user to coordinate the store with their interceptor provider. Potentially the store could become part of the interceptor provider protocol so that the client could still back `cacheKeyForObject`/`clearCache` onto the provider's store.\r\n\r\nAn alternative would be to eliminate the store from the interceptor provider, and ensure that in the client the store is set correctly on the provider so that they always line up.\r\n\r\nLastly, if maintaining backwards compatibility is key, the store from the provider and the store from the client could be compared at the end of the client initialiser, and an error raised if they are not exactly the same object.","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"Is there a particular using you're not passing in the `store` parameter for `client` on that last version? eg: \r\n\r\n```swift\r\nlet cache = InMemoryNormalizedCache()\r\nlet store = ApolloStore(cache: cache)\r\nlet provider = LegacyInterceptorProvider(store: store)\r\nlet networkTransport = RequestChainNetworkTransport(interceptorProvider: provider, endpointURL: baseURL)\r\nlet client = ApolloClient(networkTransport: networkTransport, store: store)\r\n```\r\n\r\nThat would ensure you have the same store in all places. \r\n\r\nI do agree it's a little overcomplicated at the moment - I do plan to keep evolving this, and I appreciate the feedback.\r\n","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"> Is there a particular using you're not passing in the store parameter for client on that last version? eg:\r\n\r\nNot particularly, but we did go through this stage on the way to our fully working version, which is pretty much what you have in your example.

To maintain compatibility we decided to use `LegacyInterceptorProvider` and add an additional interceptor that did what our preflight delegate implementation had previously done, hence ending up with needing to pass the store into two different places, and this getting out of sync in two different ways before we realised the implicit dependency between those two places.\r\n\r\nAlso, just realised that the 3rd code example in the issue body is roughly what's in `Network.swift` in the docs here: https://www.apollographql.com/docs/ios/tutorial/tutorial-mutations/ – following the docs here will result in an invalid construction of the networking stack I think.\r\n\r\nHaving thought about this a bit more, I think there's a more common way this could also be done incorrectly:\r\n\r\n```swift\r\nlet provider = LegacyInterceptorProvider()\r\nlet networkTransport = RequestChainNetworkTransport(interceptorProvider: provider, endpointURL: baseURL)\r\nlet client = ApolloClient(networkTransport: networkTransport, store: store)\r\n```\r\n\r\nIf not manually constructing a store at all, but instantiating a custom interceptor provider, there are two different stores being used and therefore it's impossible to clear the cache of the \"real\" one, but no error would be raised clearing the cache of the unused one.\r\n\r\nIt's possible I've missed somewhere that the stores get \"joined up\" – I'm new to Swift and don't know much about the Apollo codebase and may not understand the intention here. Apologies if that's the case!\r\n\r\n- - -\r\n\r\nI think there are 3 possible options here (although very open to more suggestions!):\r\n\r\n1. Eliminate the store from the ApolloClient entirely, leave it up to the user to coordinate the store with their interceptor provider. User will need to hold a reference to it for setting/getting the cache key, or clearing the cache.\r\n\r\n2. Eliminate the store from the interceptor provider init, have the client inject it into the interceptor provider. This way the user only has one place to pass it in, and if they don't the default one is still the same.\r\n\r\n3.

I just spent a fair amount of time debugging this issue, which I think could be resolved by removing some default values in one or both the `ApolloClient`'s and `LegacyInterceptorProvider`'s initializers. The problem is as follows:\r\n\r\n``` swift\r\nlet interceptorProvider: LegacyInterceptorProvider = .init() // More likely to use your own subclass for authentication\r\nlet transport: RequestChainNetworkTransport = .init(\r\n interceptorProvider: interceptorProvider,\r\n endpointURL: baseUrl.appendingPathComponent(\"graphql\")\r\n)\r\nlet client: ApolloClient = .init(\r\n networkTransport: transport\r\n)\r\n```\r\n\r\nThe above code creates two separate `ApolloStore`'s with default caches of `InMemoryNormalizedCache()` for both the `LegacyInterceptorProvider` and for the `ApolloClient`. When going to invalidate your cache here, you will invalidate one of the caches (the ApolloStore one), but the InterceptorProvider's cache will remain untouched, which is where results seem to be fetched from, thus making it impossible to actually invalidate the cache.

Thanks. \r\n\r\n> TokenAddingInterceptor from docs adds Authorization header to request not depending if its request or response. Is that how it should be?\r\n\r\nYes - the idea of that is that you put it first so that it is the first change applied before a request goes out. \r\n\r\n> RequestChainNetworkTransport have additionalHeaders - shouldn't this be interceptor?\r\n\r\nThese are intended to be additional headers that must be added to every single request, and which do not change (for example, an API key or a language setting). The interceptors are intended for things which may change (for example, a user's authentication token). \r\n\r\n> there is AutomaticPersistedQueryInterceptor and also autoPersistQueries on RequestChainNetworkTransport what should I use?\r\n\r\nThe short answer is both - `autoPersistQueries` tells you whether auto-persisted queries should be used at all, and the interceptor does the work of checking for APQ-related errors and auto-retrying when needed. Essentially, `autoPersistQueries` tells you if you should send APQ hashes outgoing, and the interceptor handles incoming responses to tell if you need to retry due to an APQ failure. \r\n\r\n> There is LegacyInterceptorProvider but something not \"legacy\" (NetworkInterceptorProvider) only mentioned in documentation. How do I create custom provider where I add only my interceptors and leave \"default\" ones untouched? NetworkInterceptorProvider from docs have 10 interceptors, LegacyInterceptorProvider have 7. Should I inherit from LegacyInterceptorProvider or should I copy one from docs and constantly track if new Interceptor will just appear in the list?\r\n\r\nYou _can_ inherit from `LegacyInterceptorProvider`, and override the method providing the array of interceptors. This is easier if you're putting interceptors at the beginning or end of the array rather than interspersing them throughout. If they're interspersed, it's likely better create your own implementation of `InterceptorProvider` and using the array provided by `LegacyInterceptorProvider` as a starting point. \r\n\r\nI will call out in release notes if any changes are made to the `LegacyInterceptorProvider`, particularly new interceptors - the intent is that the core interceptors should not change. \r\n","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"I was going through a similar thinking process as @RolandasRazma yesterday doing the same 0.33->0.36 migration.

At this stage, we want to catch the error, perform automatically a relogin(call `login` mutation), which basically will return a new auth token and after all that re-execute the failed request(query/mutation).\r\nAs far as I managed to understand, the best way to do this is through `ApolloErrorInterceptor`, which I basically did. I created a custom `ApolloErrorInterceptor`, returned it in `InterceptorProvider.additionalErrorInterceptor`.\r\nThe first problem I met is that it seems that not absolutely all errors get through this interceptor. Which left me without ideas on how to continue, but since this new apollo sdk approach is pretty fresh, I also left some space to consider it might be a bug, `full stop`.\r\n\r\nNow my question is: what is the correct way of handling errors?

However, when Apollo iOS sends queries to the server, it does so without any line breaks using Swift's `.appending()` method. Then when the server calculates the SHA, due to the lack of line breaks, the operation ID is different and the error is thrown. Strangely enough, however, I noticed the StarWars API actually [manually adds line breaks](https://github.com/apollographql/apollo-ios/blob/06c357b7e98fb7abcddc02ca8aeb96cc8475d263/Sources/StarWarsAPI/API.swift#L1051) in its generated code, which mine doesn't. \r\n\r\nI believe I'm using the latest version of Apollo Codegen and Apollo iOS.

You can see the code changes in-place in [this PR](https://github.com/apollographql/apollo-ios/pull/1341). I will be updating this RFC with feedback as it is received. \r\n\r\n## Why The Change?\r\n\r\n`HTTPNetworkTransport` allows you to hook into various delegates to accomplish various things. There are several limitations to this approach: \r\n\r\n- Users can only do things that are specifically supported by delegates.\r\n- Asynchronous use of delegates without callbacks is basically impossible.\r\n- Any time we want to add a new feature, we need to add a new delegate method and handle it, creating additional complexity.\r\n- There is no flexibility in terms of order of operations, particularly around whether data should be returned to the UI before being written to the cache.\r\n\r\nThe other major issue driving this update is that the current networking stack is *deeply* tied to the current cache architecture. This isn't ideal for many reasons, the biggest of which is that the cache likely to change in relation to the [Swift Codegen Rewrite](https://github.com/apollographql/apollo-ios/issues/939). \r\n\r\n## What is proposed? \r\n\r\nThe proposed new architecture uses the Interceptor pattern to create a customizable request chain. This means users can hook into the system at any point during the request creation or data processing process. \r\n\r\nThis also means that the pieces which will need to be swapped out for the Swift Codegen Rewrite are more clearly defined, and less tied to the actual parsing operation. \r\n\r\nFinally, this also opens the opportunity for different patterns than we already support, such as writing to the cache *after* returning data to the UI instead of before, or creating an array of interceptors which hit the network first, then hit the cache if nothing was returned. \r\n\r\n### New Protocols\r\n\r\n- **`FlexibleDecoder`**: This is mostly going to be helpful for the `Codable` implementation down the line, but this will allow anything conforming to `Decoder` to be used to decode data.\r\n- **`Parseable`**: This is a wrapper that allows us to continue to support non-`Codable` parsing alongside `Codable` parsing, while keeping us able to constrain and construct things generically. A default implementation for `Codable` will be provided.\r\n- **`ApolloInterceptor`**: This is an interface which allows you to add an asynchronous handler to perform any necessary work, such as fetching credentials and reading or writing from the cache, asynchronously. \r\n \r\n ```swift\r\n public protocol ApolloInterceptor: class {\r\n \r\n /// Called when this interceptor should do its work.\r\n ///\r\n /// - Parameters:\r\n /// - chain: The chain the interceptor is a part of.\r\n /// - request: The request, as far as it has been constructed\r\n /// - response: [optional] The response, if received\r\n /// - completion: The completion block to fire when data needs to be returned to the UI.\r\n func interceptAsync(\r\n chain: RequestChain,\r\n request: HTTPRequest,\r\n response: HTTPResponse?,\r\n completion: @escaping (Result, Error>) -> Void)\r\n }\r\n ```\r\n \r\n Default implementations of `ApolloInterceptor` for both Legacy (ie, non Swift Codegen) networking and Swift Codegen networking will be provided.\r\n- **`InterceptorProvider`** This protocol will be used to quickly create a new array of interceptors for a given request:\r\n\r\n ```swift\r\n public protocol InterceptorProvider {\r\n \r\n /// Creates a new array of interceptors when called\r\n ///\r\n /// - Parameter operation: The operation to provide interceptors for\r\n func interceptors(for operation: Operation) -> [ApolloInterceptor]\r\n }\r\n ```\r\n This design allows for both flexibility (you can return different interceptors for different types of requests, for instance) and isolation (each request will have its own unique set of interceptors, reducing the possibility of different requests stomping on each other). \r\n \r\n Two default interceptor providers are set up: \r\n - **`LegacyInterceptorProvider`** will provide interceptors mimicking the current stack \r\n - **`CodableInterceptorProvider`** will provide interceptors for the forthcoming Swift Codegen Rewrite's network stack. \r\n- **`ApolloErrorInterceptor`** will allow you to have additional checks whenever an error is about to be returned. This will be optional to implement, and no default implementation is provided.\r\n\r\n ```swift\r\n /// Asynchronously handles the receipt of an error at any point in the chain.\r\n ///\r\n /// - Parameters:\r\n /// - error: The received error\r\n /// - chain: The chain the error was received on\r\n /// - request: The request, as far as it was constructed\r\n /// - response: [optional] The response, if received\r\n /// - completion: The completion closure to fire when the operation has completed. Note that if you call `retry` on the chain, you will not want to call the completion block in this method.\r\n func handleErrorAsync(\r\n error: Error,\r\n chain: RequestChain,\r\n request: HTTPRequest,\r\n response: HTTPResponse?,\r\n completion: @escaping (Result, Error>) -> Void)\r\n ```\r\n \r\n### New Classes\r\n\r\n- **`HTTPRequest`** This object will hold all the information related to a request before it hits the network, with the `toURLRequest()` method creating an actual `URLRequest` based on all the information in the request. This is subclass-able (and will mostly be using subclasses). \r\n\r\n ```swift\r\n open class HTTPRequest {\r\n\r\n open var graphQLEndpoint: URL\r\n open var operation: Operation\r\n open var contentType: String\r\n open var additionalHeaders: [String: String]\r\n open var clientName: String? = nil\r\n open var clientVersion: String? = nil\r\n open var retryCount: Int = 0\r\n public let cachePolicy: CachePolicy\r\n\r\n public init(graphQLEndpoint: URL,\r\n operation: Operation,\r\n contentType: String,\r\n additionalHeaders: [String: String],\r\n cachePolicy: CachePolicy = .default)\r\n \r\n open func toURLRequest() throws -> URLRequest\r\n\r\n open func addHeader(name: String, value: String)\r\n }\r\n ```\r\n \r\n - **`JSONRequest`** subclass of `HTTPRequest` will handle creating requests with JSON, which will be the vast majority of requests with operations. This is where handling of auto-persisted queries is also layered in: \r\n\r\n ```swift\r\n public class JSONRequest: HTTPRequest {\r\n \r\n public let requestCreator: RequestCreator\r\n \r\n public let autoPersistQueries: Bool\r\n public let useGETForQueries: Bool\r\n public let useGETForPersistedQueryRetry: Bool\r\n public var isPersistedQueryRetry = false\r\n \r\n public let serializationFormat = JSONSerializationFormat.self\r\n\r\n public init(operation: Operation,\r\n graphQLEndpoint: URL,\r\n additionalHeaders: [String: String] = [:],\r\n cachePolicy: CachePolicy = .default,\r\n autoPersistQueries: Bool = false,\r\n useGETForQueries: Bool = false,\r\n useGETForPersistedQueryRetry: Bool = false,\r\n requestCreator: RequestCreator = ApolloRequestCreator())\r\n }\r\n ```\r\n \r\n - **`UploadRequest`** subclass of `HTTPRequest` will handle multipart file uploads:\r\n\r\n ```swift\r\n public class UploadRequest: HTTPRequest {\r\n \r\n public let requestCreator: RequestCreator\r\n public let files: [GraphQLFile]\r\n public let manualBoundary: String? \r\n public let serializationFormat = JSONSerializationFormat.self\r\n \r\n public init(graphQLEndpoint: URL,\r\n operation: Operation,\r\n additionalHeaders: [String: String] = [:],\r\n files: [GraphQLFile],\r\n manualBoundary: String? = nil,\r\n requestCreator: RequestCreator = ApolloRequestCreator()) \r\n }\r\n ```\r\n\r\n- **`HTTPResponse`** will represent the objects returned and/or parsed from the server:\r\n\r\n ```swift\r\n /// Designated initializer\r\n ///\r\n /// - Parameters:\r\n /// - response: The `HTTPURLResponse` received from the server.\r\n /// - rawData: The raw, unparsed data received from the server.\r\n /// - parsedResponse: [optional] The response parsed into the `ParsedValue` type. Will be nil if not yet parsed, or if parsing failed.\r\n public class HTTPResponse {\r\n public var httpResponse: HTTPURLResponse\r\n public var rawData: Data\r\n public var parsedResponse: GraphQLResult?\r\n }\r\n ```\r\n\r\n- **‌`RequestChain`** will handle the interaction with the network for a single operation. \r\n\r\n ```swift\r\n public class RequestChain: Cancellable {\r\n\r\n /// Creates a chain with the given interceptor array\r\n public init(interceptors: [ApolloInterceptor])\r\n \r\n /// Kicks off the request from the beginning of the interceptor array.\r\n ///\r\n /// - Parameters:\r\n /// - request: The request to send.\r\n /// - completion: The completion closure to call when the request has completed.\r\n public func kickoff(\r\n request: HTTPRequest, \r\n completion: @escaping (Result) -> Void)\r\n \r\n /// Proceeds to the next interceptor in the array.\r\n /// \r\n /// - Parameters:\r\n /// - request: The in-progress request object\r\n /// - response: [optional] The in-progress response object, if received yet\r\n /// - completion: The completion closure to call when data has been processed and should be returned to the UI.\r\n public func proceedAsync(\r\n request: HTTPRequest, \r\n response: HTTPResponse?,\r\n completion: @escaping (Result) -> Void)\r\n \r\n /// Cancels the entire chain of interceptors.\r\n public func cancel()\r\n \r\n /// Restarts the request starting from the first inteceptor.\r\n ///\r\n /// - Parameters:\r\n /// - request: The request to retry\r\n /// - completion: The completion closure to call when the request has completed.\r\n public func retry(\r\n request: HTTPRequest,\r\n completion: @escaping (Result) -> Void)\r\n }\r\n ```\r\n- **`RequestChainNetworkTransport`** provides an implementation of `NetworkTransport` which uses an `InterceptorProvider` to create a request chain for each request. \r\n ```swift\r\n public class RequestChainNetworkTransport: NetworkTransport {\r\n \r\n public init(interceptorProvider: InterceptorProvider,\r\n endpointURL: URL,\r\n additionalHeaders: [String: String] = [:],\r\n autoPersistQueries: Bool = false,\r\n cachePolicy: CachePolicy = .default,\r\n requestCreator: RequestCreator = ApolloRequestCreator(),\r\n useGETForQueries: Bool = false,\r\n useGETForPersistedQueryRetry: Bool = false)\r\n }\r\n ```\r\n\r\n### Changes to existing Protocols and Classes\r\n\r\n- **`ApolloStore`** will no longer require a `GraphQLQuery` explicitly for fetching data from the store. It will instead return an error if the `GraphQLOperationType` is not `.query`. This change is necessary to avoid going down an enormous rabbit hole with generics since `GraphQLOperation` has an associated type. \r\n- The **`NetworkTransport`** protocol will get a new method to be implemented: \r\n\r\n ```swift\r\n func sendForResult(operation: Operation,\r\n completionHandler: @escaping (Result, Error>) -> Void) -> Cancellable\r\n ```\r\n \r\n This will avoid the double-wrapping of `GraphQLResponse` around the `GraphQLResult` so that only the `GraphQLResult` is actually returned. The `send` method will eventually be deprecated and removed. \r\n- **`ApolloClient`** will get a new `sendForResult` method which calls into the `sendForResult` method added to `NetworkTransport`.\r\n\r\n## How will this work in practice? \r\n\r\nInstantiating a new legacy client manually will look like this: \r\n\r\n```swift\r\nlazy var legacyClient: ApolloClient = {\r\n let url = URL(string: \"http://localhost:8080/graphql\")!\r\n \r\n let store = ApolloStore(cache: InMemoryNormalizedCache())\r\n let provider = LegacyInterceptorProvider(store: store)\r\n let transport = RequestChainNetworkTransport(interceptorProvider: provider, endpointURL: url)\r\n \r\n return ApolloClient(networkTransport: transport)\r\n}()\r\n```\r\n\r\nIdeally I'll be able to transparently swap out the existing `HTTPNetworkTransport` for this so that this would be the under-the-hood setup on `ApolloClient`, but this may involve a transition period. \r\n\r\nCalls to the client will look like this: \r\n\r\n```swift\r\nlegacyClient.fetchForResult(query: HeroNameQuery()) { result in\r\n switch result {\r\n case .success(let graphQLResult):\r\n print(graphQLResult.data?.hero?.name ?? \"Name not found\")\r\n case .failure(let error):\r\n print(\"Unexpected error: \\(error)\")\r\n }\r\n}\r\n```\r\n\r\nNote that this is VERY similar to how they look on the surface at the moment, which is intentional. \r\n","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"Overall this looks great.

It will instead return an error if the GraphQLOperationType is not .query. This change is necessary to avoid going down an enormous rabbit hole with generics since GraphQLOperation has an associated type.\r\n\r\n> I'm a little bit fuzzy on what this change is. If not a GraphQLQuery, what will the input for data fetching from the store be? Can you clarify for me?\r\n\r\nBasically, we have the `GraphQLOperation` protocol, with an associated type of `Data`, and its three sub-protocols, `GraphQLQuery`, `GraphQLMutation`, and `GraphQLSubscription`. Previously, we were limiting what operations could read from the cache to `GraphQLQuery`, since in theory that's the only place getting something from the cache would matter. \r\n\r\n`HTTPRequest` only requires a specification of `GraphQLOperation`, but when making a call into the cache, we can't use the `Blah is GraphQLQuery` method of figuring out whether a `GraphQLOperation` is a query because of the `associatedType` on `GraphQLOperation`. \r\n\r\nI tried about 15 different workarounds for this and this is the only one that wasn't monstrously over-complicated - everything else involved some mild-to-completely bizarre type erasure strategies. I'm not totally against those, but I think in this case the benefits of going that way were vastly outweighed just changing the gating of this a bit.","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"and if you have specific feedback on #1341 I'd love to hear it - just be aware that there's definitely a lot that's WIP (thus the TODOs)","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"OK, I've done some poking around on the request for a typed error parameter, and I don't think it's going to be doable at the interceptor level.\r\n\r\nWhen I tried to add this in, any existing `Error` I tried to return would cause a \"Cannot convert value\" build failure: \r\n\"Screen\r\n\"Screen\r\n\r\nIt'd make the interceptors a lot harder to keep independent if they all had to have exactly the same type of error. It also wouldn't be possible for me to have default implementations return errors without having `TypedError` conform to some other protocol that allows me to return an underlying arbitrary error. Ultimately, I think that adds too much complexity for general use cases.\r\n\r\nI think if you want to write your own typed wrapper that takes whatever's returned and feeds it into something with an `underlying` error that's easier to switch on, that could work.

The last interceptor in the chain (the tail of the list) would be responsible for performing the actual HTTP request, in most cases—but not always!\r\n\r\nSometimes you want to terminate the chain with something that makes an HTTP request, but other times the terminal link might provide its own data (for example, mock data during tests). Sometimes you might want to split a request between multiple downstream links, or choose among several servers that can handle different kinds of requests (or load-balance the same type of request between multiple servers, entirely on the client). It's hard to represent branching structures like that as an array, because it's no longer really a list, but a dynamic tree. But if each interceptor gets to make its own decisions about how it passes requests to the rest of the chain (and how it handles the responses), the branching can be hidden as an implementation detail, with each interceptor abstracting over everything downstream from it.\r\n\r\nI don't know enough Swift to anticipate specific ways in which this approach might be tricky, but it seems like it should be possible to give the interceptor chain more of a recursive, potentially tree-like structure. That's worked pretty well on the web, in the sense that I haven't had to worry very much about the `ApolloLink` system, even as I've changed large portions of the rest of the library.\r\n\r\nFor reference, here's an overview of `ApolloLink` concepts that I've found useful in the past: https://www.apollographql.com/docs/link/overview/","author":{"__typename":"User","login":"benjamn","id":"MDQ6VXNlcjU3NTA=","name":"Ben Newman"}},{"__typename":"IssueComment","body":"I think one huge, huge difference is that things like cancellation, retry, and thread management can be handled through javascript's `Observable` reactive system. \r\n\r\nThat just isn't doable without either using Combine (which would require dropping everything below iOS 12, and is unfortunately a non-starter with a number of our larger users) or adding some kind of Reactive library as a dependency (which I am loathe to do because of the *massive* number of dependency conflicts it could introduce). \r\n\r\nHowever, I think you're right that splitting out methods for request setup vs response handling is a good idea - this could at least help reduce the number of things that need to be optional on `HTTPResponse`. \r\n\r\nWill futz with this tomorrow.

From the perspective of links earlier in the chain, a request that succeeded after several retries looks exactly like one that succeeded on the first try, except that it might have taken a bit longer. If retrying was something you could implement in a perfectly generic way for all interceptors, it might make sense to hoist it to a higher layer of the system (maybe into `RequestChain`), but in practice retrying tends to be sensitive to application concerns (different logic for different queries, even), so I think it makes sense to push it down into a part of the system that can be customized by application developers.\r\n\r\nI think we can agree it's important for interceptors to be able to perform any kind of async work as an implementation detail, which requires a uniformly asynchronous API. Both `Observable` and Combine provide that kind of API, but they are both probably overkill, or at the very least they would need to earn their way into a system like this. I believe you that Combine is not worth it for iOS, but then again I'm not sure `Observable` is totally defensible for JS applications, either.","author":{"__typename":"User","login":"benjamn","id":"MDQ6VXNlcjU3NTA=","name":"Ben Newman"}},{"__typename":"IssueComment","body":"> When I tried to add this in, any existing `Error` I tried to return would cause a \"Cannot convert value\" build failure:\r\n\r\nfrom this error it looks like you changed the signature of `handleErrorAsync` to:\r\n```swift\r\nfunc handleErrorAsync(\r\n error: TypedError,\r\n chain: RequestChain,\r\n request: HTTPRequest,\r\n response: HTTPResponse,\r\n completion: @escaping (Result) -> Void)\r\n```\r\n\r\nwhile I was thinking something like: \r\n```swift\r\nfunc handleErrorAsync(\r\n error: Error, // keep this one untyped so that you can pass anything you need\r\n chain: RequestChain,\r\n request: HTTPRequest,\r\n response: HTTPResponse,\r\n completion: @escaping (Result) -> Void) // but allow users to wrap the internal errors in their own custom types\r\n```\r\nso that you can give a default implementation that does not wrap the error type: \r\n```swift \r\nextension ApolloErrorInterceptor where TypedError == Error {\r\n// default interceptor with a untyped completionHandler\r\n```\r\n\r\nsorry I wasn't clear with the previous message.

That said, it is the only conclusion that survived our tests. Having found this https://stackoverflow.com/questions/62612056/why-dispatchqueue-global-still-alive-after-deinit on StackOverflow, we think that the problem stems from the queue keeping alive the instance of the `URLSession` created in `URLSessionClient` in some fashion.\r\n\r\nThis causes multiple retains climbing up the dependence graph of:\r\n- URLSession\r\n- URLSessionClient\r\n- HTTPNetworkTransport\r\n- ApolloClient\r\n- Objects in our code that calls ApolloClient ...\r\n\r\n### OUR SOLUTION\r\nAdding the following to `HTTPNetworkTransport` fixes both our issues:\r\n```\r\ndeinit {\r\n self.client.session.invalidateAndCancel()\r\n}\r\n```\r\n\r\nWe understand that this is most probably not the solution you will want to implement but it might help as a starting point to formulate something that will not jeopardize others that use your framework.\r\n\r\n### OUR INVESTIGATION\r\nIt should be said that we took the liberty to try this as there was code in the `URLSessionClient` for `deinit` that clears all tasks. We surmised that clearing the tasks in that situation did not cause a problem for calls in progress, meaning that clients of the framework should not expect the calls to complete if they stop holding their instance of `ApolloClient`.\r\n\r\nBut we noticed that the `deinit` in the `URLSessionClient` was never called even when its parent `HTTPNetworkTransport` `deinit` was called. We then noticed that the `HTTPNetworkTransport` was never deallocated even though its `deinit` was called.\r\n\r\nThat made us realize that something further down the line was probably holding things recursively. Implementing our solution, everything gets deallocated and for some reason, further ApolloClients return their calls successfully.\r\n\r\n### CONCLUSION\r\nAdvice on how to go forward from here would be greatly appreciated.\r\nThanks in advance for your help.

So in my app I'm having a list of conversations, so I'm creating a `watch` on a query that returns the list of conversations, this is something like that:\r\n\r\n```\r\nuser {\r\n uuid\r\n firstName\r\n lastName\r\n conversations {\r\n uuid\r\n unreadMessagesCount\r\n }\r\n}\r\n```\r\n\r\n> In the app we use the `uuid` key to handle cache, so we make sure to always pass `uuid` in our queries to automatically handle cache update.\r\n\r\nSo the role of the watcher I'm talking about is both to update existing conversations and also be able to catch when a new conversation is created (it can happen and not be initiated by the user, we then trigger an event from the backend that is listen from a subscription in the app). When this event happens it returns something like that\r\n\r\n```\r\nevent {\r\n newConversation {\r\n conversation {\r\n uuid\r\n unreadMessagesCount\r\n // This is the part that adds the new conversation to the existing ones of the users in the cache\r\n user {\r\n uuid\r\n conversations {\r\n uuid\r\n unreadMessagesCount\r\n }\r\n } \r\n }\r\n }\r\n}\r\n```\r\n\r\nIt works great, meaning that when this event happens, the watcher is being called with the newly created conversation, but the issue is that any new cache update for that specific conversation doesn't trigger the watcher again.\r\n\r\nAfter investigating a bit, I realised that the cache is being updated because if I'm adding 3 new messages into the new conversation (setting the `unreadMessagesCount` to 3), the watcher doesn't get called but then if I add 1 new message into an old one, the watcher is being called with both the new message on the old conversation and the 3 new on the new one. \r\n\r\nSo it really seems like `watch` is not being called again for changes on an item that wasn't in a collection when the `watch` was initially made. I've also take a look at https://github.com/apollographql/apollo-ios/issues/281 and making a `fetch` on the same query again after the event doesn't fix the issue.\r\n\r\nLet me know if I'm not clear on something as the whole thing is a bit complicated to explain.","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"Hi!

Apologize for noise.)_\r\n\r\n# Problem\r\n\r\nWe have done some experiments in adopting pagination and encountered a few issues. I am looking for a recommendation on how to extract paginated results that do achieve two of my main goals. For the context, we have a mobile application that has screens that show paginated content that allows infinite vertical scrolling.\r\n\r\n1. Perform pagination in a responsible manner without any lag on the UI\r\n2. Ability to watch any changes to the items retrieved across all pages\r\n\r\nFor example, assume the following schema\r\n\r\n```\r\ntype PageResult {\r\n cursor: String\r\n hasMore: Bool\r\n items: [String]\r\n}\r\nquery {\r\n getItems(cursor: String): PageResult\r\n}\r\n```\r\n\r\nHere are the approaches we tried:\r\n\r\n## Approach 1: Follow the suggestion as per the [Apollo iOS tutorial blog](https://www.apollographql.com/docs/ios/tutorial/tutorial-pagination/)\r\n\r\n1. Load the first page with no cursor with cache policy that writes data back to the cache\r\n2. Load the second page with the cursor and follow the same for the next pages with cache policy that writes data back to the cache\r\n\r\n### Issues with Approach 1\r\n\r\n#### 1. Zombie records:\r\n\r\nFollowing the query path approach to generate cache key, the First page will be written under cache key \"QUERY\\_ROOT.getPage-cursor\", while subsequent pages will hold the items under the cache key \"QUERY\\_ROOT.getItems-cursor-page2cursor\", \"QUERY\\_ROOT.getItems-cursor-page3cursor\", and so on..\r\n\r\nIn our case, The page cursors are generated run time and only valid until the first page is refreshed again to get a new cursor. Following this approach, We notice that all the pages that were previously fetched will never be deleted after re-fetching the first page and hence get accumulated as the user fetches more pages and re-fetches leading to larger cache size over time. Not to mention the more number of records, the higher the read time.\r\n\r\n#### 2. Cannot watch updates to items from the second page onwards:\r\n\r\nWe want to set up a GraphQLQueryWatcher on the paginated query, such that any changes to the items, including items from all the pages retrieved so far. However, Looking at the implementation of the GraphQLQueryWatcher, it appears that with this approach, Watcher will notify only for the items returned from the first page since dependent keys for the watcher includes only keys from the first page.\r\n\r\n## Approach 2: Manually merge data from subsequent pages into the first page\r\n\r\nIn order to solve the Approach #1 Issue #2, We took inspiration from [Apollo react Pagination](https://www.apollographql.com/docs/react/data/pagination/#cursor-based) which does the following:\r\n\r\n1. Load the first page with no cursor with cache policy that writes data back to the cache\r\n2. Load the second page, and so on, with `fetchIgnoringCacheCompletely` cache policy and manually write the data into the First-page query.\r\n\r\n### Issues with Approach 2\r\n\r\n#### 1. Writes are slow\r\n\r\nAs we can notice in Step #2, we merge the previous page with data pulled from the next page and re-write the entire data back. As we fetch more pages, the write latency increases.\r\n\r\n#### 2 Latency of reading the first page exponentially increases\r\n\r\nSince we merge data from all pages into the first page, reading the first page exponentially increases based on the number of items present in the cache. This is more evident with queries that have an increasing number of attributes that are non-scalar data types in the query as the batch loader does round trip to the database for each attribute. With our sample of data, the read time for a query with medium complex schema has clocked 10 seconds to read 150 items on an iPhone XS device.","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"Hey @bharath2020 - just a heads up that I'm bogged down at the moment but this is a *very* good question that I need to work on a better answer to (and that we should have a *way* better answer to overall for mobile), and I think messing around with the tutorial is probably a good place to start with it. And you are very correct that 10 seconds to read 150 items is 🤮. \r\n\r\nIn terms of what you can try while I'm digging out from under what I'm dealing with now, there's the `cacheKeyForObject` closure that you can use to generate a custom cache key. For most items you should be able to cache by ID, and that should avoid having to rewrite all the data if it's not necessary. \r\n\r\nI'm going to leave this open for the community to respond more - I know this has been done well, but my knowledge of details isn't there because I'm focused on other parts of the SDK at the moment. \r\n","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"Thanks, @designatednerd for the response.\r\n\r\n> For most items you should be able to cache by ID, and that should avoid having to rewrite all the data if it's not necessary.\r\n\r\nInteresting. In approach #2, Given that I am appending items from `morePage` back to `firstPage` and issuing a re-write of data for the first-page query, I am curious how would the store understand to not overwrite data referencing items in the first page? In other words, I understand `cacheKeyForObject` would reduce the number of records written to the database, but even with normalized cache, there would be unnecessary overwrites (in this case the items in the first page) that would add to the write latency. Please correct me If I am wrong.\r\n\r\nP.S. I have cacheKeyForObject enabled in my sample, and timings were taken after. The only part where I would not be able to generate a cache key is for the `PageResult` type, as `cacheKeyForObject` does not expose the variables (or field arguments) used to generate the type, in this case, it is the `cursor` provided for `getItems(cursor:)` query.","author":{"__typename":"User","login":"bharath2020","id":"MDQ6VXNlcjkwMzUzNg==","name":null}},{"__typename":"IssueComment","body":"Again, my knowledge of the cache is not as deep as it should be, but my understanding is you'd be rewriting the references with IDs rather than the entire object and its entire tree of changes. This almost certainly has some unnecessary work, but it would likely constitute a lot *less* unnecessary work than without the `cacheKeyForObject`. \r\n\r\nAnd again, this is not working as well as we want it to. We have some changes to the cache slated for [phases 2 and 3 of the ongoing Swift codegen rewrite](https://github.com/apollographql/apollo-ios/issues/939), and making things less annoying for pagination is one of the major things I want to do within that work. \r\n\r\nWish I had a better answer for you.

When this event happens it returns something like that\r\n\r\n```\r\nevent {\r\n newConversation {\r\n conversation {\r\n uuid\r\n unreadMessagesCount\r\n // This is the part that adds the new conversation to the existing ones of the users in the cache\r\n user {\r\n uuid\r\n conversations {\r\n uuid\r\n unreadMessagesCount\r\n }\r\n } \r\n }\r\n }\r\n}\r\n```\r\n\r\nIt works great, meaning that when this event happens, the watcher is being called with the newly created conversation, but the issue is that any new cache update for that specific conversation doesn't trigger the watcher again.\r\n\r\nAfter investigating a bit, I realised that the cache is being updated because if I'm adding 3 new messages into the new conversation (setting the `unreadMessagesCount` to 3), the watcher doesn't get called but then if I add 1 new message into an old one, the watcher is being called with both the new message on the old conversation and the 3 new on the new one. \r\n\r\nSo it really seems like `watch` is not being called again for changes on an item that wasn't in a collection when the `watch` was initially made. I've also take a look at https://github.com/apollographql/apollo-ios/issues/281 and making a `fetch` on the same query again after the event doesn't fix the issue.\r\n\r\nLet me know if I'm not clear on something as the whole thing is a bit complicated to explain.","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"To add more to this, I feel like this is not related to collections only.

That means subscription results are not actually published to the store, and thus will not trigger watchers. (@benoitletondor I think that would at least explain your initial bug report).\r\n\r\n2) That doesn't yet explain why queries and mutations would also fail to trigger watchers (assuming those are not using the `WebSocketTransport`). There is a possibility for misconfiguration however, which would lead to inadvertently having multiple stores (see https://github.com/apollographql/apollo-ios/issues/1438). Could some of you be bitten by this maybe?\r\n\r\n3) Using a custom `NetworkTransport` also currently ignores the cache completely (see https://github.com/apollographql/apollo-ios/pull/1442 for an in progress PR to work around this).

Also, I may just be missing things!\r\n\r\nThere are two ways to set up an `ApolloStore` for the networking in Apollo, and unless both are done, in the same way, I believe there can be inconsistencies.\r\n\r\nFor example, we previously did this in our `ApolloClient` setup:\r\n\r\n```swift\r\nlet networkTransport = HTTPNetworkTransport(url: baseURL)\r\nlet cache = InMemoryNormalizedCache()\r\nlet store = ApolloStore(cache: cache)\r\nlet client = ApolloClient(networkTransport: networkTransport, store: store)\r\n```\r\n\r\nWhen upgrading to the newest version of Apollo, we originally re-wrote this as:\r\n\r\n```swift\r\nlet provider = LegacyInterceptorProvider()\r\nlet networkTransport = RequestChainNetworkTransport(interceptorProvider: provider, endpointURL: baseURL)\r\nlet cache = InMemoryNormalizedCache()\r\nlet store = ApolloStore(cache: cache)\r\nlet client = ApolloClient(networkTransport: networkTransport, store: store)\r\n```\r\n\r\nAs far as I can tell (please tell me if I'm wrong!) this has set up a store that is now not being used at all. We can still call `client.clearCache()` or `client.cacheKeyForObject` and it will use the store that we created, but this would _not_ affect the store being used by the interceptors.\r\n\r\nSimilarly, we could have configured a more complex cache setup, but that would not be used by the interceptors.\r\n\r\nIf we corrected this in the following way...\r\n\r\n```swift\r\nlet cache = InMemoryNormalizedCache()\r\nlet store = ApolloStore(cache: cache)\r\nlet provider = LegacyInterceptorProvider(store: store)\r\nlet networkTransport = RequestChainNetworkTransport(interceptorProvider: provider, endpointURL: baseURL)\r\nlet client = ApolloClient(networkTransport: networkTransport)\r\n```\r\n\r\n...this would also introduce bugs because while our correct store is being used for the networking, `client.clearCache` or `client.cacheKeyForObject` are pointing to the `ApolloClient`'s default store from its init method.\r\n\r\n## Versions\r\n\r\n- `apollo-ios` SDK version: 0.34.1\r\n- Xcode version: 12.0\r\n- Swift version: 5.3\r\n\r\n## Steps to reproduce\r\n\r\nSee above for the process that can lead to incorrect use. This is roughly the steps that we took while upgrading Apollo to 0.34.x – i.e. we went through two invalid implementations before reaching one that we believe is valid.\r\n\r\n## Further details\r\n\r\nAs mentioned above, this isn't really a bug, but I think it's a design issue that could be improved. My recommendation would be to eliminate the store from the `ApolloClient` entirely, and leave it up to the user to coordinate the store with their interceptor provider. Potentially the store could become part of the interceptor provider protocol so that the client could still back `cacheKeyForObject`/`clearCache` onto the provider's store.\r\n\r\nAn alternative would be to eliminate the store from the interceptor provider, and ensure that in the client the store is set correctly on the provider so that they always line up.\r\n\r\nLastly, if maintaining backwards compatibility is key, the store from the provider and the store from the client could be compared at the end of the client initialiser, and an error raised if they are not exactly the same object.","comments":{"__typename":"IssueCommentConnection","nodes":[{"__typename":"IssueComment","body":"Is there a particular using you're not passing in the `store` parameter for `client` on that last version? eg: \r\n\r\n```swift\r\nlet cache = InMemoryNormalizedCache()\r\nlet store = ApolloStore(cache: cache)\r\nlet provider = LegacyInterceptorProvider(store: store)\r\nlet networkTransport = RequestChainNetworkTransport(interceptorProvider: provider, endpointURL: baseURL)\r\nlet client = ApolloClient(networkTransport: networkTransport, store: store)\r\n```\r\n\r\nThat would ensure you have the same store in all places. \r\n\r\nI do agree it's a little overcomplicated at the moment - I do plan to keep evolving this, and I appreciate the feedback.\r\n","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"> Is there a particular using you're not passing in the store parameter for client on that last version? eg:\r\n\r\nNot particularly, but we did go through this stage on the way to our fully working version, which is pretty much what you have in your example.

To maintain compatibility we decided to use `LegacyInterceptorProvider` and add an additional interceptor that did what our preflight delegate implementation had previously done, hence ending up with needing to pass the store into two different places, and this getting out of sync in two different ways before we realised the implicit dependency between those two places.\r\n\r\nAlso, just realised that the 3rd code example in the issue body is roughly what's in `Network.swift` in the docs here: https://www.apollographql.com/docs/ios/tutorial/tutorial-mutations/ – following the docs here will result in an invalid construction of the networking stack I think.\r\n\r\nHaving thought about this a bit more, I think there's a more common way this could also be done incorrectly:\r\n\r\n```swift\r\nlet provider = LegacyInterceptorProvider()\r\nlet networkTransport = RequestChainNetworkTransport(interceptorProvider: provider, endpointURL: baseURL)\r\nlet client = ApolloClient(networkTransport: networkTransport, store: store)\r\n```\r\n\r\nIf not manually constructing a store at all, but instantiating a custom interceptor provider, there are two different stores being used and therefore it's impossible to clear the cache of the \"real\" one, but no error would be raised clearing the cache of the unused one.\r\n\r\nIt's possible I've missed somewhere that the stores get \"joined up\" – I'm new to Swift and don't know much about the Apollo codebase and may not understand the intention here. Apologies if that's the case!\r\n\r\n- - -\r\n\r\nI think there are 3 possible options here (although very open to more suggestions!):\r\n\r\n1. Eliminate the store from the ApolloClient entirely, leave it up to the user to coordinate the store with their interceptor provider. User will need to hold a reference to it for setting/getting the cache key, or clearing the cache.\r\n\r\n2. Eliminate the store from the interceptor provider init, have the client inject it into the interceptor provider. This way the user only has one place to pass it in, and if they don't the default one is still the same.\r\n\r\n3. If maintaining backwards compatibility is key, the store from the provider and the store from the client could be compared at the end of the client initialiser, and an error raised if they are not exactly the same object.\r\n\r\n","author":{"__typename":"User","login":"danpalmer","id":"MDQ6VXNlcjIwMjQwMA==","name":"Dan Palmer"}},{"__typename":"IssueComment","body":"Good catch on the example in the tutorial, that's definitely an error.\r\n\r\nThere are (rare) instances where someone intentionally wants to use different stores, but you're right that most of the time, that's not the case. \r\n\r\nI think of the options you propose, 2 probably makes the most sense.

I just spent a fair amount of time debugging this issue, which I think could be resolved by removing some default values in one or both the `ApolloClient`'s and `LegacyInterceptorProvider`'s initializers. The problem is as follows:\r\n\r\n``` swift\r\nlet interceptorProvider: LegacyInterceptorProvider = .init() // More likely to use your own subclass for authentication\r\nlet transport: RequestChainNetworkTransport = .init(\r\n interceptorProvider: interceptorProvider,\r\n endpointURL: baseUrl.appendingPathComponent(\"graphql\")\r\n)\r\nlet client: ApolloClient = .init(\r\n networkTransport: transport\r\n)\r\n```\r\n\r\nThe above code creates two separate `ApolloStore`'s with default caches of `InMemoryNormalizedCache()` for both the `LegacyInterceptorProvider` and for the `ApolloClient`. When going to invalidate your cache here, you will invalidate one of the caches (the ApolloStore one), but the InterceptorProvider's cache will remain untouched, which is where results seem to be fetched from, thus making it impossible to actually invalidate the cache.

Thanks. \r\n\r\n> TokenAddingInterceptor from docs adds Authorization header to request not depending if its request or response. Is that how it should be?\r\n\r\nYes - the idea of that is that you put it first so that it is the first change applied before a request goes out. \r\n\r\n> RequestChainNetworkTransport have additionalHeaders - shouldn't this be interceptor?\r\n\r\nThese are intended to be additional headers that must be added to every single request, and which do not change (for example, an API key or a language setting). The interceptors are intended for things which may change (for example, a user's authentication token). \r\n\r\n> there is AutomaticPersistedQueryInterceptor and also autoPersistQueries on RequestChainNetworkTransport what should I use?\r\n\r\nThe short answer is both - `autoPersistQueries` tells you whether auto-persisted queries should be used at all, and the interceptor does the work of checking for APQ-related errors and auto-retrying when needed. Essentially, `autoPersistQueries` tells you if you should send APQ hashes outgoing, and the interceptor handles incoming responses to tell if you need to retry due to an APQ failure. \r\n\r\n> There is LegacyInterceptorProvider but something not \"legacy\" (NetworkInterceptorProvider) only mentioned in documentation. How do I create custom provider where I add only my interceptors and leave \"default\" ones untouched? NetworkInterceptorProvider from docs have 10 interceptors, LegacyInterceptorProvider have 7. Should I inherit from LegacyInterceptorProvider or should I copy one from docs and constantly track if new Interceptor will just appear in the list?\r\n\r\nYou _can_ inherit from `LegacyInterceptorProvider`, and override the method providing the array of interceptors. This is easier if you're putting interceptors at the beginning or end of the array rather than interspersing them throughout. If they're interspersed, it's likely better create your own implementation of `InterceptorProvider` and using the array provided by `LegacyInterceptorProvider` as a starting point. \r\n\r\nI will call out in release notes if any changes are made to the `LegacyInterceptorProvider`, particularly new interceptors - the intent is that the core interceptors should not change. \r\n","author":{"__typename":"User","login":"designatednerd","id":"MDQ6VXNlcjE5NzY0OTg=","name":"Ellen Shapiro"}},{"__typename":"IssueComment","body":"I was going through a similar thinking process as @RolandasRazma yesterday doing the same 0.33->0.36 migration.

At this stage, we want to catch the error, perform automatically a relogin(call `login` mutation), which basically will return a new auth token and after all that re-execute the failed request(query/mutation).\r\nAs far as I managed to understand, the best way to do this is through `ApolloErrorInterceptor`, which I basically did. I created a custom `ApolloErrorInterceptor`, returned it in `InterceptorProvider.additionalErrorInterceptor`.\r\nThe first problem I met is that it seems that not absolutely all errors get through this interceptor. Which left me without ideas on how to continue, but since this new apollo sdk approach is pretty fresh, I also left some space to consider it might be a bug, `full stop`.\r\n\r\nNow my question is: what is the correct way of handling errors?
