Apple recently required that anyone using 3rd party authentication (google, fb, etc) in their iOS app, must also provide support for Apple ID signin. That is not an unreasonable request. I was able to implement the signin without too much difficulty. However, when it came to doing a server-side validation of the signin via the Apple API; it was an absolute POS blackbox.
Their documentation and server responses provided no indication of why the validation failed. I searched the docs and forums; it was clear that a ton of other people had the same problem with absolutely no clues into resolving the issue. So I just gave up on it. Total waste of time.
