I have a Sticker Pack target added to my app. The Deployment Target for the app is iOS 9.0 and for the Sticker Pack I normally just leave it at default (currently 12.1).
Now, with Xcode 10 I get a warning when delivering my app via Application Loader. With Xcode 9 this would not be a problem, and no warning was given when delivering.
ITMS-90747
Architecture incompatible with MinimumOSVersion. The app bundle at ***.appex specifies a MinimumOSVersion of 12.1 but contains a 32-bit architecture that is unsupported on iOS 12 or later.
In an attempt to remove the warning I changed the Sticker Pack's Deployment Target to iOS 9.0 to match the app. But this now gives an error when delivering.
ITMS-90208
Invalid Bundle. The bundle ***.appex does not support the minimum OS Version specified in the Info.plist.
I don't know what to do to remove the warning. Is it even important?
