When can we delete Apple App Identifiers? I see an old answer that specifies that "I believe we can only delete app ids that haven't been used in the store at all. Once an app id has been exposed to the store, it remains on record (and cannot be re-used) whether you delete an app or not." What does being "exposed to the store" mean exactly? does adding an identifier in the identifies list in developer.apple.com/account/resources/identifiers/list qualify as the "identifier being exposed to the App Store"?

Why are images added to Resource folder in Playgrounds still not being found?
