I'm experiencing this problem with iOS 15.4. I have to switch to an iOS 13 simulator to make it work, but then the rest of my app doesn't behave as expected, so I have to switch back to iOS 15.4 simulator and hard code a user ID. This is not a sustainable workflow. I'm very surprised that a native capability is not working in iOS simulator.
Can someone from apple please let us know when this will be fixed? this seems to be an issue for over a year now without any response.
OK Ive decided to ditch sign in with apple. I will not offer this to my customers because it is too difficult to get working.
Same problem here, any solution yet?
facing the same issue in xcode 12.3 and simulator iOS 14.3
This is a complete joke... absolutely no comment by Apple on this... Apple doesn't care about its developers at all... The only solution: buy an iPhone!
