How do I add the Keychain sharing feature to my App ID?

Question

I am using Firebase to create a Login portal. I first connected an Apple account to Xcode which didn't have an iPhone or iPad connected to it and this error popped up. Now I have removed that account and added another one which has an iPhone connected to it but still the error pops up. How do I resolve it?

It's a bit late, but if anyone else runs into this issue:

I had the same issue. I was using com.test.TestApp as my bundle identifier (which in turn made it the KeychainGroup ID when activating).

Changing my bundle identifier under Project > Targets > AppName > General > Identity > Bundle Identifier to something more unique like com.myLastName.TestApp solved it for me. Be sure to also adjust the KeychainGroup identifier to match your newly changed bundle identifier.
