Made all the setup for sign in with apple, but when pressing on continue and passing Face ID check I am getting "Sign Up not completed" error. However, no error is thrown to the delegate.
Then I tried to create a test project with my friend's Paid developer account and everything was fine, no errors. I haven't connected to the API, just trying to print Email and Fullname.
May be something is wrong with my company's Developer account?
I had created Auth Key with Apple Sign selected in which is never used. When I remove the unused Auth Key it worked.
I had the same issue. I did followings and it was working fine.
Hope this works!
I recently encountered this error and the root problem turned out to be some back-end data problem with my Apple account.
I ultimately had to raise an Apple Technical Support Request, generate some debug information for them, and then they ultimately fixed their back-end data for my account. The overall process took just under three weeks.
For me the reason was , I was using my bundle id in the place where Apple services ID should be entered in cognito user pool.
