Facing an issue with Sign in with Apple (SIWA) in tvOS

Hello,

I am facing the following issue while trying to Sign in with Apple (SIWA) on the tvOS simulator.

I have enabled the entitlements for SIWA in the project target. And the same steps are working fine in the iOS simulator.

Steps to reproduce the issue:

1. Upon requesting for SIWA on custom button tap, a full-screen layover displayed for the password of apple id (No option for choosing email relay was given)
2. Upon entering the correct password I get the callback in the error delegate.

Error in the error delegate:

error Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1000 "(null)"

Below is the code-snippet attached for the whole process.

I have done all the steps required as per the official document of SIWA for iOS.

FYI: The same code is working for iOS for me but not for the tvOS. I have tested SIWA in the iPhone simulator while development and now trying the same with the tvOS but it isn't working.

Below is my code.

Here, function setup( ) is called on viewDidLoad of ViewController

    private func setup() {
        if #available(tvOS 13.0, *) {
                        
            let appleIDProvider = ASAuthorizationAppleIDProvider()
            
            appleIDProvider.getCredentialState(forUserID: "myapp.identifiers.currentUserIdentifier") { (credential, error) in

                switch credential {
                case .authorized:
                    print("authorized for sign in")
                    break
                case .notFound, .revoked, .transferred:
                    print("ready to logout")
                    break
                default:
                    print("Apple sign in credential state unidentified")
                }
                
            }
        }
    }

Inside the action method of the custom SIWA button, my code looks like

if #available(tvOS 13.0, *) {
            let appleIDProvider = ASAuthorizationAppleIDProvider()
            let request = appleIDProvider.createRequest()
            request.requestedScopes = [.fullName, .email]
            
            let authorizationController = ASAuthorizationController(authorizationRequests: [request])
            authorizationController.delegate = self
            authorizationController.presentationContextProvider = self
            authorizationController.performRequests()
        }

The presentation anchor is set in the extension of ViewController

extension ENWelcomeScreenViewController: ASAuthorizationControllerPresentationContextProviding {
    /// - Tag: provide_presentation_anchor
    @available(tvOS 13.0, *)
    func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {
        return self.view.window!
    }
}

And finally, the error delegate, in which I am receiving the callback.

/// - Tag: did_complete_error
    @available(tvOS 13.0, *)
    func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) {
        print("error \(error)")
    }

Is apple sign in supported in the tvOS simulator? Or I am doing something wrong here?

Any leads are highly appreciated.
