How to get around Apple app ID insanity

Question

As you all know, Apple changed how Xcode works such that you can\'t ever create an app with a previously used app ID, even if you\'re just writing test apps to use locally.

Answer 1

I had this and the other answers here didn't fix the problem. I solved it by opening Window > Devices, finding my device, right-clicking it to "Show Provisioning Profiles", and then deleting a bunch of the profiles there.

Then it worked!
