I'm working on an iOS app using CloudKit. I followed Apple's advice in the link below to test in the simulator with a newly created Apple id. This Apple id is working fine for logins in my browser. However when trying to use it in my simulator it keeps telling me the username/password is incorrect, which is really not true.
I tried the same with my developer apple ID and there it works fine. Afaik the settings regarding 2FA are the same. Resetting the simulator didn't solve it also.
Any ideas?
