Recently I have developed Sign in with Apple feature in my iOS app. It was almost similar like Facebook login.
By the way I faced an issue that I couldn't get a user's email after the initial sign up. Then I found a link that Apple engineer answered.
So if you are testing Sign in with Apple feature go to iOS Settings and remove the previous sign in permission. Then you might save the user information such as the email address into your database.
