When trying to register a new services ID, I see the following text:
We recommend using a reverse-domain name style string (i.e., com.domainname.appname). It cannot contain an asterisk (*).
I have an App and associated Bundle and App ID. I made the bundle ID and app ID the same. Call it X.Y.Z. Now, I want to add the Sign in With Apple functionality, but when I use X.Y.Z for the services ID identifier, I get an error:
An attribute in the provided entity has invalid value An App ID with Identifier 'X.Y.Z' is not available. Please enter a different string.
Could someone confirm that I cannot use the same App/ Bundle ID for the service ID identifier, or that I might be doing something else wrong.
I have checked this bundle ID/ App ID is owned by the same account. I noticed a few other people who had 2 accounts in their Xcodes which they mixed up. I only have 1 account.
It turns out you can't use the same ID for both applications and services. I just made a unique identifier for the service, and it works fine.
