I am developing an app in swift, and I use AWS mobile services for authentication and AWS Lambda to do some backend processing. I had everything working fine, and one day (after leaving the app for a month or so), it started throwing this error:

 GetId failed. Error is [Error Domain=com.amazonaws.AWSCognitoIdentityProviderErrorDomain Code=-1000 "Authentication delegate not set" UserInfo {NSLocalizedDescription=Authentication delegate not set}]

 Unable to refresh. Error is [Error Domain=com.amazonaws.AWSCognitoIdentityProviderErrorDomain Code=-1000 "Authentication delegate not set"

It's killing me, because it was already working. What could have changed?

In appDelegate, I have:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {



        // Uncomment to turn on logging, look for "Welcome to AWS!" to confirm success

        AWSDDLog.add(AWSDDTTYLogger.sharedInstance)

        AWSDDLog.sharedInstance.logLevel = .error



        // Instantiate AWSMobileClient to get AWS user credentials

        return AWSMobileClient.sharedInstance().interceptApplication(application, didFinishLaunchingWithOptions:launchOptions)

    }

It actually throws the error before I make any invocation, so I think the lines above may be triggering the problem?

To login, I do the following, in my main viewController:

override func viewDidLoad() {

        super.viewDidLoad()



        if !AWSSignInManager.sharedInstance().isLoggedIn {

            presentAuthUIViewController()

        }

        else{

            getCredentials()

        } 

        ...

        }



func presentAuthUIViewController() {

        let config = AWSAuthUIConfiguration()

        config.enableUserPoolsUI = true

        config.backgroundColor = UIColor.white

        config.logoImage = #imageLiteral(resourceName: "logoQ")

        config.isBackgroundColorFullScreen = true

        config.canCancel = true



        AWSAuthUIViewController.presentViewController(

            with: self.navigationController!,

            configuration: config, completionHandler: { (provider: 

            AWSSignInProvider, error: Error?) in

                if error == nil {

                    self.getCredentials()

                } else {

                    // end user faced error while loggin in, take any required action here.

                }

        })

    }



    func getCredentials() {

        let serviceConfiguration = AWSServiceConfiguration(region: .USEast1, credentialsProvider: nil)

        let userPoolConfiguration = AWSCognitoIdentityUserPoolConfiguration(clientId: "id",

                                                                            clientSecret: "secret",

                                                                            poolId: "id")

        AWSCognitoIdentityUserPool.register(with: serviceConfiguration, userPoolConfiguration: userPoolConfiguration, forKey: "key")

        let pool = AWSCognitoIdentityUserPool(forKey: "key")

        if let username = pool.currentUser()?.username {

            userName = username

        }

It loggs in, and I retrieve the user name.

Any tips? I followed some of the instructions in other posts but they didn't work, plus what most disconcerts me is that it was working!

Thanks in advance

So, not 100% sure of what was going on, but as I understand it there was a problem with the credentials for the user in the user pool. I reset the password and all started working fine again!

I anyone needs more detail just ask, and if anyone understands this better let me know..
