  <pre><code>com.apple.AuthenticationServices.Authorization Error Code 1000
  </code></pre>
  
  <p>I'm using the following code to sign in to Apple</p>
  
  <pre><code>var appleIdProvider = new ASAuthorizationAppleIdProvider();
  var request = appleIdProvider.CreateRequest();
  request.RequestedScopes = new ASAuthorizationScope[] { ASAuthorizationScope.Email, ASAuthorizationScope.FullName };
  var authController = new ASAuthorizationController(new[] { request });
  authController.Delegate = this;
  authController.PresentationContextProvider = this;
  authController.PerformRequests();
  ...
  [Export("authorizationController:didCompleteWithAuthorization:")]
  public void DidComplete(ASAuthorizationController controller, ASAuthorization authorization)
  {
  ...
  }
  
  [Export("authorizationController:didCompleteWithError:")]
  public void DidComplete(ASAuthorizationController controller, NSError error)
  {
  ...
  }
  </code></pre>
  
  <ul>
  <li>I checked Apple Sign-in in the Entitlements.plist</li>
  <li>I created app id in the management console, verified my domain. Even web auth works already.</li>
  <li>I tried to switch provisioning profile to one with apple sign in.</li>
  </ul>
  
  <p>What could be the reason of this error?</p>
