Expected Behavior

Being able to make any request after login. Can't initialize data in request() -> urlSession.dataTask

Actual Behavior

Error when invoking api.userFollows(...):
Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value
Error when invoking getInstagramData()=api.user(...):
decoding(message: "The data couldn’t be read because it is missing.") The operation couldn’t be completed. (SwiftInstagram.InstagramError error 0.)

Steps to Reproduce the Problem

1. Login button action

`
static func loginInstagram(from: UINavigationController, completion: @escaping (Error?) -> Void){
let api = Instagram.shared

    // Login
    //print("Instragam Login")
    api.login(from: from, withScopes: [.basic, .publicContent], success: {
        completion(nil)
    }, failure: { error in
        print(error.localizedDescription)
    })

}
`
2. Get data button action

`
static func getInstagramData() {
let api = Instagram.shared

    api.user("self", success: { userList in
        print(SwiftyJSON.JSON(userList))
    }, failure: { error in
        print(error)
        print(error.localizedDescription)
    })

}
`

However this works:
Alamofire.request("https://api.instagram.com/v1/users/self?access_token="+api.retrieveAccessToken()!).responseJSON(completionHandler: { response in if let result = response.result.value { let swiftyJSON = JSON(result) print(swiftyJSON) }
