I get the following 'Attribute Unavailable' warning when I turn on 'Scroll Edge' for a tab bar in the Interface Builder in XCode 13.0. Tab Bar Scroll Edge Appearance before iOS 15.0 I have my target set to iOS 12.1, and I understand that this option is not available in these past versions. However all works ok in previous versions of iOS, and the setting gets ignored as you would hope/expect. What is the recommended way of dealing with warnings like these, considering you can't turn off individual warnings in XIB files?

After a recent app update, I started getting a few user reports of a problem opening the app (seemed to be crashing on startup). I asked them to turn on AirPlane mode any try again, and they then get the following message when trying to open the app: "Unable to verify app: A connection to the app store is required for the first launch of '{appName}' on this iPhone. Please connect to the internet and try again."This is obviously coming from iOS not the app, and I am not getting any particular crash reports relating to startup issues, so it does not seem to be getting as far as the app code. The above message seems to also imply this is the case. These users are regular users of the app, so it has clearly been launched in the past.I really can't find out much info about this error message (other that it is related to licensing), so am a little baffled as to what is going on. Can anyone shed any light on what may be happening?
