Change log

0.33.0-beta1

  • SPECTACULARLY BREAKING: The networking stack for HTTP requests has been completely rewritten. This is described in great detail in the RFC for the networking changes, as well as the updated documentation for Advanced Client Creation. Please, please, please file bugs or requests for clarification of the docs as soon as possible. Note that all changes until the networking stack comes out of beta will live on the betas/networking-stack branch. (#1341)

v0.32.1

  • Improves invalidation of a URLSesionClient to include cancellation of in-flight operations. (#1376)

v0.32.0

  • Fixes an issue that would occur when a GraphQL query watcher's dependent keys would not get updated. (#1375)
  • Adds an extensions dictionary property to GraphQLResult. (#1370)
  • Makes a couple of response parsing helpers public for advanced use cases. (#1372)

v0.31.0

  • Adds the ability to pause and resume a WebSocket connection without dumping existing subscriptions. (#1335)

  • Adds an initializer to SQLiteNormalizedCache that takes a SQLite.swift DatabaseConnection to more easily allow setup of pre-configured connections. (#1330)

  • Addresses a retain cycle that could cause memory leaks when using multiple instances of HTTPNetworkTransport.

    NOTE: If you're using URLSessionClient outside the context of HTTPNetworkTransport, make sure to call invalidate() on it when whatever is holding onto it hits deinit() to prevent leaks. (#1366)

v0.30.0

  • BREAKING: Updates the CLI to 2.30.1 to fix a long-standing issue where when generating operation IDs and their related JSON file, the correct operations + fragments would be used in generating the operation ID, but not output with the JSON file. This will slightly change the output in API.swift, but it also means we can remove a related workaround from the iOS SDK. (#1316)
  • BREAKING: Removed the Cartfile which declared our dependencies, since we're now internally managing them with SPM, and newer versions of Carthage just use the SPM dependencies. Note that this can cause issues if you need to use a fork of dependencies, or if you're using an older version of Carthage. (#1311)
  • POSSIBLY BREAKING: Works around an issue that could cause some attempts to store untyped JSON dictionaries to throw unexpected errors about optional encoding. This also added handling of creating a dictionary from a JSONValue, which may cause problems if you've already implemented this yourself, but which should mostly just replace the need to implement it yourself. Please file issues ASAP if you run into problems here. (#1317)
  • Works around an issue causing some attempts to store arrays of JSON dictionaries to have arbitrary key ordering. (#1281)
  • Adds clearer error descriptions to a few errors. (#1295)

v0.29.1

  • Updates the CLI to 2.28.3 to fix an issue where linter failures would cause a silent failure exit. (#1284, #1288](#1288))
  • Adds a check to swift scripting that the downloaded file has the correct SHASUM, otherwise forcing redownload. (#1288)

v0.29.0

  • NEW: Swift scripting is officially out of Beta! Please check out our updated guide to integration. The tutorial should be updated to recommend using Swift Scripting within the next week or so. NOTE: The shell script is not deprecated yet, but will be shortly. (#1263)
  • BREAKING: Found some workarounds to conditional conformance and updated all extensions to use the apollo.extensionMethod syntax introduced in 0.28.0. (#1256)
  • BREAKING: Moved a few things into the new ApolloCore library. For CocoaPods and SPM users, this should be automatically picked up by your package manager. Carthage users, you will need to drag the new ApolloCore library into your project manually as you have with the other Apollo libs. (#1256)
  • BREAKING: Updated to version 2.28.0 of the Apollo JS CLI. This includes moving a bunch of static let allocations to computed static vars to prevent memory overuse. (#1246)
  • Made GraphQLGetTransformer and its methods public and made a couple more methods on MultipartFormData public. (#1273)
  • Fixes an issue when uploading multiple files for different variables. (#1279, special thanks to #1081)
  • Fixes a crash when encoding GraphQLVariable objects which conform to JSONEncodable. (#1262)

v0.28.0

  • BREAKING: Changed a few things in the ApolloCodegen library to use object.apollo.extensionMethod syntax rather than object.apollo_extensionMethod. There's a few things that are still using apollo_ notation due to constraints around conditional conformance, but you should particularly check your swift scripts for changes around FileManager APIs. (#1183)
  • BREAKING: NormalizedCache now has a method for explicitly clearing the cache synchronously, in addition to the existing method to clear it asynchronously. If you've got a custom NormalizedCache implementation, you'll need to add an implementation for this method. (#1186)
  • Fixed race conditions in URLSessionClient that were causing unexpected behavior. Turns out concurrency is hard! (#1227)
  • Improved handling of a dependent key update cancelling an in-flight server fetch on a watcher. (#1156)
  • Added option to Swift Codegen to pass in a prefix for custom scalars. (#1216)
  • Added ability to change a header on a websocket connection and automatically reconnect. (#1224)

v0.27.1

  • Better defense against multithreading crashes in URLSessionClient. (#1184)
  • Fix for watchOS availability for URLSessionClient. (#1175)

v0.27.0

  • BREAKING: Replaced calls directly into the closure based implementation of URLSession with a delegate-based implementation called URLSessionClient.

    • This (finally) allows background session configurations to be used with ApolloClient, since background session configurations immediately error out if you try to use the closure-based URLSession API.

    • This makes a significant change to the initialization of HTTPNetworkTransport if you're using a custom URLSession: Because URLSession must have its delegate set at the point of creation, URLSessionClient is now creating the URL session. You can initialize a URLSessionClient with a URLSessionConfiguration. if before you were using:

      let session = URLSession(configuration: myCustomConfiguration)
let url = URL(string: "http://localhost:8080/graphql")!
let transport = HTTPNetworkTransport(url: url,
                                     session: session)

      You will now need to use:

      let client = URLSessionClient(sessionConfiguration: myCustomConfiguration)
let url = URL(string: "http://localhost:8080/graphql")!
let transport = HTTPNetworkTransport(url: url,
                                     client: client)

    • If you were passing in a session you'd already set yourself up to be the delegate of to handle GraphQL requests, you'll need to subclass URLSessionClient and override any delegate methods off of URLSessionDelegate, URLSessionTaskDelegate, or URLSessionDataDelegate you need to handle. Unfortunately only one class can be a delegate at a time, and that class must be declared when the session is instantiated.

      Note that if you don't need your existing delegate-based session to do any handling for things touched by Apollo, you can keep it completely separate if you'd prefer.

    • This does not change anything at the point of calls - everything is still closure-based in the end

      Please file bugs on this ASAP if you run into problems. Thank you! (#1163)

v0.26.0

  • BREAKING, though in a good way: Updated the typescript CLI to 2.27.2, and updated the script to pull from a CDN (currently backed by GitHub Releases) rather than old Circle images. This should significantly increase download performance and stability. (#1166)
  • BREAKING: Updated the retry delegate to allow more fine-grained control of what error to return if an operation fails in the process of retrying. (#1128, #1167)
  • Added support to the Swift scripting package to be able to use multiple headers when downloading a schema. (#1153)
  • Added the ability to set the SSL trust validator on a websocket. (#1124)
  • Fixed an issue deserializing custom scalars in ApolloSQLite. (#1144)

v0.25.1

  • Repoints download link to our CDN for the CLI for people on 0.25.0 who can't upgrade to 0.26.0 or higher immediately.

v0.25.0

  • BREAKING: Updated the swift-tools version to 5.2 in Package.swift. Note that if you're using swift-tools 5.2, you'll need to update the syntax of your Package.swift file and specify the name of the library manually for Apollo. (#1099, #1106)
  • POSSIBLY BREAKING: Upgraded the typescript CLI to 2.26.0. No changes were found in test frameworks, but this could theoretically break some stuff. (#1107, #1113)
  • NEW: Added the ability to set Starscream's underlying enableSOCKSProxy to better allow debugging web sockets in tools like Charles Proxy. (#1108)
  • Fixed several issues using paths with spaces in the Swift Codegen. (#1092, #1097).
  • ApolloCodegenLib is now properly passing the header argument last when downloading a schema. (#1096)
  • Automatic Persisted Queries now also work with mutations. (#1110)

v0.24.1

  • Repoints download link to our CDN for the CLI for people on 0.24.0 who can't upgrade to 0.26.0 or higher immediately.

v0.24.0

  • BREAKING: Updated GraphQLResponse to be generic over the response type rather than the operation type. This will allow more flexibility for generic modifications to methods that need to use GraphQLResponse. (#1061)
  • BREAKING: Updated the file URL-based initializer of GraphQL to throw with a clear error instead of failing silently. Removed the ability to pass in an input stream since that can't be recreated on a failure. Updated initializers take either raw Data or a file URL so that the input stream can be recreated on a retry. (#1086, #1089)
  • In the Swift Package Manager based codegen, made sure that the folder the CLI will be downloaded to is created if it doesn't exist. (#1069)

v0.23.3

  • Repoints download link to our CDN for the CLI for people on 0.23.x who can't upgrade to 0.26.0 or higher immediately.

v0.23.2

  • Changed the @available flags added in 0.23.1 to #if os(macOS), since the former is runtime and the latter is compile time, to work around a bug where SwiftUI compiles the ApolloCodegenLib library even if it's not included in the target being previewed. (#1066)
  • Added support for omitDeprecatedEnumCases command line option I missed for ApolloCodegenOptions (#1053)

v0.23.1

  • Added some @available flags to prevent accidental compilation of ApolloCodegenLib on platforms other than macOS. (#1041)
  • Made the Query on GraphQLQueryWatcher public so it can be referenced. (#1037)

v0.23.0

  • BETA: Now available, SPM-based code generation, Phase 0 of our transition to Swift Codegen.

    Note that the underlying codegen is still using apollo-tooling, but that will change as we proceed with Phase 1 of the Swift Codegen Project, generating the code in Swift.

    Documentation is available at our Swift Scripting page.

    When this gets to the final version this will supersede existing codegen, so please file bugs galore on this so we can get it good to go as quickly as possible. Thank you! (#940, #1033)\

  • Fixed some memory leaks in our internal Promises implementation. (#1016)

v0.22.1

  • Repoints download link to our CDN for the CLI for people on 0.22.0 who can't upgrade to 0.26.0 or higher immediately.

v0.22.0

  • BREAKING: Updated CLI to v2.22.1, including a bunch of fixes on the Swift side:
    • Marked files which are generated as @generated
    • Added documentation to the constructors of input structs
    • Added additional type annotations to improve compile times.
  • BREAKING: Updated delegate in HTTPNetworkTransport to be a weak var and to not be passed in as a parameter to the initializer. (#990, #1002)
  • Added a lock to InMemoryNormalizedCache to reduce possible race conditions. (#552)
  • Added the ability to not send duplicates on a websocket. (#1004)
  • Fixed an issue that could lead to an undefined cache key in the SQLite library. (#991)
  • Fixed an issue where existing fetch operations in a watcher would not be canceled before a new one was started. (#1012)

v0.21.1

  • Repoints download link to our CDN for the CLI for people on 0.21.0 who can't upgrade to 0.26.0 or higher immediately.

v0.21.0

  • BREAKING, but by popular request: Removed the requirement that the clientName and clientVersion on NetworkTransport, and added a default implementation so custom implementations don't need to set these up themselves. (#954)

v0.20.1

  • Repoints download link to our CDN for the CLI for people on 0.20.0 who can't upgrade to 0.26.0 or higher immediately.

v0.20.0

  • Fixed a bunch of data races in ApolloWebSocket. (#880)
  • Updated ApolloWebSocket to depend on Apollo in Package.swift since there is a dependency there. (#906)
  • POSSIBLY BREAKING Updated Swift tools verson in package declaration to 5.1. (#883)

v0.19.1

  • Repoints download link to our CDN for the CLI for people on 0.19.0 who can't upgrade to 0.26.0 or higher immediately.

v0.19.0

  • NEW: Added a retry delegate to allow retries based on GraphQL errors returned from your server, not just network-level errors. NOTE: Be careful with which errors you retry for - the mere presence of an error doesn't necessarily indicate a full failure since GraphQL queries can return partial results. (#770)
  • NEW: Automatically generates ApolloEngine/ApolloGraphManager headers based on your main bundle's ID and version number. These can also be configured when you set up your NetworkTransport if you need something more granular for different versions of your application. (#858)
  • POSSIBLY BREAKING: The NetworkTransport protocol is now class-bound. If you built your own NetworkTransport implementation instead of one of the ones included with the library, this now must be a class instead of a struct. (#770)
  • POSSIBLY BREAKING: Removed an unzip method for arrays of arays which we were not using. However, since it was public, we figured we should let you know. (#872)
  • Bumped Starscream dependency to 3.1.1. (#873)

v0.18.2

  • Repoints download link to our CDN for the CLI for people on 0.18.x who can't upgrade to 0.26.0 or higher immediately.

v0.18.1

  • Removes TSAN from run on schemes to fix Carthage issue. (#862)

v0.18.0

  • POSSIBLY BREAKING: Updated CLI to no longer be directly bundled, but to be downloaded if needed. This allows us to avoid bloating the iOS repo with the CLI zip, and to make it easier to test different versions of the CLI in the future. This change should automatically download the updated CLI version for you.

    Note one significant change from prior bundled versions: If you are connected to the internet when you download the iOS dependency through SPM/Carthage/CocoaPods, you will now need to build your target while still connected to the internet in order to download the proper version of the CLI. Once the correct version of the CLI is downloaded, internet access should no longer be necessary to build. If you disconnect from the internet before the correct version downloads, you will not be able to build. (#855)

  • Updated version of CLI to download to 2.21.0. (#855) This includes:

    • Ability to have the codegen ignore deprecated enum cases by using the --omitDeprecatedEnumCases flag
    • Fix for generating input fields for null values

  • Fixes a number of weak references with closures. Note that this may reveal some places you weren't hanging onto a strong reference to your ApolloClient object, which will cause it to get deallocated. (#854)

v0.17.0

  • NEW: Support for Automatic Persisted Queries. This feature allows you to send the hash of a query to your server, and if the server recognizes the hash, it can perform the whole query without you having to send it again. This is particularly useful for large queries, since it can reduce the amount of data you have to send from your user's device pretty significantly. (#767)
  • BREAKING: Removed old script files which have been deprecated. If you were still using these, please check out the updated codegen build step setup instructions to get up and running with the run-bundled-codegen script. (#820)
  • POSSIBLY BREAKING: Updated bundled CLI to v2.19.1. Please check out the CLI changelog for full details, but this version actually moves to using multi-line Swift strings for queries. If you prefer to have condensed queries, it also introduces a --suppressSwiftMultilineStringLiterals flag which produces single-line queries stripped of whitespace. (#831)
  • Fixed a couple places we were not using LocalizedError properly. (#818)

v0.16.1

  • Updated the way run-bundled-codegen checks whether the bundled codegen has already been unzipped and has node locally. (#806)
  • Updated how default parameters are provided for RequestCreatorProtocol. (#804)

v0.16.0

  • BREAKING: We've switched to a much simpler setup which does not involve NPM in order to use our CLI. This requires updating your build scripts. Please follow the updated instructions for setting up the build script here. The existing build script will continue to work until the next minor release, at which point it will be removed. (#766)
  • Included CLI version fixes issues which showed up in 0.15.2.
  • BREAKING: We've removed all public references to our internal Promise implementation, which was never intended to be public. (#709)
  • Fixed a deadlock in a transaction. (#763, #365)
  • Added a RequestCreatorProtocol to allow you to more easily muck with and/or mock creating multipart requests. (#771)
  • Fixed an issue causing problems building with SPM in Xcode 11. (#784)

v0.15.3

  • Revert CLI update from 0.15.2 due to unexpected build issues.

v0.15.2

  • Update Apollo CLI requirement to 2.18. This should pull in a couple fixes to the CLI:

    • Way better escaping of identifiers, types, and strings (Tooling #1515)
    • Fix compiler warning when an optional has a .none case (Tooling #1482)

    If you run into any weird build issues after this update, try deleting your local node_modules folder and rebuilding before filing an issue. (#760)

  • Better handling of the localizedDescription for HTTPResponseError. (#756)

v0.15.1

  • Add platform name to framework bundle identifier to work around a change to app store submission. Please see the PR for more details. (#751)
  • Expose the initializer for GraphQLQueryWatcher so it can actually be instantiated. (#750)

v0.15.0

  • BREAKING: Finally swapped out URLSessionConfiguration on initializer for HTTPNetworkTransport to use URLSession directly instead. If you were previously passing in a configuration, first hand it to a URLSession instance and then pass that instance into the initializer.

    This allows many new things including:

    • Support for background sessions
    • Easier mocking through NSURLProtocol
    • Certificate pinning
    • Self-signed certificates
    • Metrics inspection
    • Authentication challenge handling

All these are pretty much entirely through the ability to use URLSessionDelegate directly since we're now accepting a URLSession you can declare yourself to be the delegate of rather than just the configuration. (#699, inspired by #265)

  • BREAKING, though hopefully in a good way: Significant updates to the Upload functionality to make it conform more closely to the GraphQL Upload Spec. Also added a goodly bit of documentation around this functionality. (#707)
  • Way better support for Swift Package Manager, especially for ApolloSQLite and ApolloWebSocket. (#674)
  • Created ApolloClientProtocol to match all public methods of ApolloClient for easier mocking. (#715, inspired by #693)

v0.14.0

  • BREAKING Updated codegen to use 2.17 of the Apollo CLI. Please see the full release notes for that version of the CLI, but in short:

    • Stops force-unwrapping and instead nil-coalesce to .none when the thing being unwrapped was a double-optional, which was causing some crashes
    • Fixes issue where removing redundant modifiers was a little too agressive
    • Fixes escaping for Self as a type name
    • Adds CaseIterable for all known cases of an enum. If you were adding this yourself previously, you'll have to take it back out.
    • Adds comment with original operation to operationDefinition, stripped excess whitespace from actual definition.

  • Added explicit support for Catalyst builds. (#688)

  • Added support for Int custom scalars. (#402)

  • Exposed clearCache directly on stores so a store being used by multiple clients can be more explicitly cleared. (#518)

  • Fixed an issue where an error on cache write would not be propagated correctly. (#673)

  • Updated supported Node version to the Long-Term Support version. (#672)

v0.13.0

PLEASE READ THESE RELEASE NOTES BEFORE INSTALLING IF YOU WERE USING AN OLDER VERSION!

  • SUPER-BREAKING: Updated a ton of completion closures that could use it to use Result instead of optional parameter / optional error. (#644). There are a few details to this one to be particularly aware of:

    • If you see a bunch of Swift build errors that are claiming Generic Parameter "Query" could not be inferred, that means you need to update your completion closure to take the single Result<Parameter, Error> parameter instead of the two (Parameter?, Error?) parameters.
    • Particularly around caching, if there are places where both parameters were nil in previous iterations, you will now get an Error. This will generally be a JSONDecodingError.missingValue, either as the direct error or as the underlying error of a GraphQLResultError. Please check out the changes to FetchQueryTests in PR #644 for a better look at how some of that has changed.

  • BREAKING: Updated the codegen to use v2.16 of the Apollo CLI. (#647). This is a major version change so some things need to be added, and some parameter names have changed:

    • You must add --target=swift so the CLI knows to generate Swift code.
    • If you were using --schema=schema.json, use --localSchemaFile="schema.json" instead (the quotes are required!).
    • If you were using --queries="$(find . -name '*.graphql')" to pass in an array of all your GraphQL files, use --includes=./*.graphql instead.

    If you get error messages about multiple versions of node when you attempt to run, delete the node_modules folder in your source root and rebuild.

    Upgrading fixes several issues:

    • operationName is now generated for all operations.
    • Trailing newlines are now added to all generated files.

  • NEW: Ability to upload files according to the GraphQL Multi-part request spec. (#626, #648, inspired by #116)

  • NEW: Now that operationName is generated for all operations, we're sending it along with all requests. (#657, inspired by #492)

  • NEW: We're also sending operationName as the X-APOLLO-OPERATION-NAME header and when an operationIdentifier is provided, sending that as the X-APOLLO-OPERATION-ID header. (#658)

  • NEW: Option to run VACUUM on your SQLite store when clearing to help obliterate all traces of data. (#652)

  • NEW: Auto-generated API documentation from inline comments. Now available on the website NOTE: Any manual changes made to markdown files will get overwritten, if you want to contribute to the docs, please add inline comments to the code and then I'll get the docs updated. (#642).

  • Made GraphQLResultError and its underlying error public for better error handling. (#655)

v0.12.0

  • BREAKING: Removed internal Result type in favor of Swift's built in Result type. This allows you to not have to prefix anything that uses the built-in result type with Swift.Result in places where you're using the Apollo SDK. (#641)
  • BREAKING: Set strict dependency versions for Starscream and SQLite.swift to prevent potential problems with Swift version conflicts. (#641).
  • BREAKING: Made Carthage dependencies for Starscream and SQLite.swift private so they're not automatically pulled in when trying to build just the main SDK with Carthage. If you're using the ApolloSQLite or ApolloWebSocket frameworks with Carthage, please read the updated documentation!. (#635, #641)
  • Fixed issue where GET requests were requiring AnyHashable instead of Any which made requests with Bool properties never send. (#628, big thanks to #624)

v0.11.1

  • Fixed missing Foundation imports for several classes that were causing issues with Buck and Swift Package Manager builds. (#620)
  • Updated version of SQLite.swift dependency to one that properly supports Swift 5. (#621)
  • Whole mess o'documentation updates. (#618)
  • Fixed a whitespace issue with one of the build scripts. (#618)
  • Made the GraphQLResult initializer public for testing. (#544)

v0.11.0

  • BREAKING: Updated Podspec to preserve paths rather than embedding scripts in the framework. Updated instructions for embedding with CocoaPods. (#575, #610)
  • NEW: At long last, the ability to update headers on preflight requests, the ability to peer into what came to the URLSession and the ability to determine if an operation should be retried. (#602)
  • NEW: Added .fetchIgnoringCacheCompletely caching option, which can result in significantly faster performance if you don't need the caching. (#551)
  • NEW: Added support for using GET for queries. (#572, #599, #602)
  • Updated lib and dependencies to use Swift 5, and say so in the Podfile. (#522, #528, #561, #592)
  • Exposed a method to ping a WebSocket server to keep it alive. (#422)
  • Handling is always done on a handler queue. (#539)
  • Added documentation on the read and update operations for watching queries. (#452)
  • Updated build scripts for non-CocoaPods installations to account for spaces in project names or folders. (#610)
  • Fixed a code generation fail if you're using MacPorts instead of Homebrew to install npm. (#591)

v0.10.1

  • Disabled bitcode in Debug builds for physical devices (#499)
  • Don't embed the Swift standard libraries by default (#501)

v0.10.0

  • Swift 5 support (#427, #475)
  • Update to newest version of Starscream (#466
  • Add ability to directly update cache with write methods (#413)
  • Add docs for read and update operations (#452)

v0.9.5

  • Add ability to pass params to Query.Data (#437)
  • Provide separate archs for the iOS Simulator (#410)
  • Actually install the correct version of Node instead of just checking for it (#434)

v0.9.4

  • Updated required version of apollo-cli to 1.9. A nice addition to 1.9.2 is that Swift Enums now conforms to Hashable enabling among other things comparision between fetch objects. (#578)
  • Fixed internal bug that caused infinite reconnection cycle when connection is lost. A reconnectionInterval was added as a workaround. (#368)
  • Fixed internal bug that prevents the wrongType case being returned by the JSONDecodingError implementation of Matchable. (#367)
  • Added delegate for WebTransport which can handle connection/reconnection/disconnection events of websocket. (#379)

v0.9.1

  • Since apollo-codegen is now part of the new apollo-cli, the build script used to generate API.swift needs to be updated. See the docs for the updated script.

v0.6.0

  • Added read and write functions for fine-grained manual store updates.

  • Added support for pluggable asynchronous caches, with an optional experimental SQLite implementation.

  • Fragments are now merged into the parent result, so you only need to go through fragments when you want to pass a fragment explicitly.

  • Generated result models are no longer immutable (but still obey value semantics).

  • Generated result models now have memberwise initializers (when they represent a concrete type) or type-specific factory methods (when they represent multiple possible types).

  • Any generated result model can be safely initialized from a JSON object (init(jsonObject:) and converted into a jsonObject.

  • Generated input objects now differentiate between a property being null and a property not being present.
