My existing iOS app has a legacy App ID prefix which does not match my Team ID.
I am planning on migrating it to my Team ID. I am aware of the potential issues with keychain access groups, however I wanted to double check that there are no issues related to "Sign in with Apple".
My app is currently the "Primary App ID" in the "Sign in with Apple" settings. The full App ID is listed there, including the prefix.
Can someone from the relevant team at Apple confirm that changing the App ID prefix to Team ID has no effect related to "Sign in with Apple"?
Hi,
For native apps, Sign in with Apple uses the bundle ID as its client identifier (ID); for websites or apps on other platforms, the Services ID associated with the primary app ID is used instead.
For an individual app, migrating to a Team ID App ID prefix will not cause any issues with your Sign in with Apple implementation. However, if you plan to use app groups for Sign in with Apple, you'll want to ensure that all child apps have the same App ID prefix as the primary app.
