“An App ID with bundle identifier X is not available. Please enter a different string” (Xcode 7.3)

Question

After updating to the latest build of Xcode 7.3 (7D175), every time I try to Export for adhoc distribution I get the above error. Everything was working fine up until the up

Answer 1

Nothing was working for me in Xcode 7.3. This can save you a lot of time, I solved it this way:

1. Xcode -> Preferences -> Accounts -> Provisioning Profiles -> Right Click them and move them to trash. Quit Xcode.

2. Member Center -> Provisioning Profiles -> All -> Deleted everything here (I have a single iOS app). Created a fresh new Profile with my app ID.

3. Member Center -> App IDs -> My App ID was of the form

Xcode iOS App ID com myDomain myApp

. If this is your case, blindly follow along -> Edit it, and try renaming it to the form

XC com myDomain myApp

-> if it says "Enter a valid name" in red, be patient a drop down will appear if your cursor is inside the Name text field - choose it and click Save. [Don't ask what's going on here, it just works - we have better things to deal with]

4. Open Xcode and click on that "Fix Issue" button which usually complicates things - surprisingly this time, it'll ease them!
