ASAuthorizationAppleIDRequest with name and mail scope returns nil values

Seems like a bug but after reading different posts on apple forums it looks like this seems to be the expected behaviour.

So some takeaways.

1. On the first time sign in with apple (signup) make sure to create user account on your backend.

2. In case of any connection error with your servers, make sure you save the user details locally (because you are not getting this next time) and keep retrying to create account on your backend.

3. For testing on device you can revoke your apple ID login for your app. After revoking it will work like a signup next time and you will get the details like (email, name, etc).

To revoke access on your device with IOS 13.

iPhone Settings > Apple Id > Password & Security > Apple ID logins > {YOUR APP} > Stop using Apple ID
