Received this error:
ITMS-90863: Apple silicon Macs support issue - The app has LSApplicationLaunchProhibited set to true. This is not supported on Mac.
TMS-90747: Architecture incompatible with MinimumOSVersion. The app bundle specifies a MinimumOSVersion of '14.1' but contains a 32-bit architecture that is unsupported on iOS 12 and later.
The first thing I noticed was that the Project Document was set to Project Format Xcode 9.3-compatible, so I changed that to Xcode 12, thinking that would eliminate the 32 bit problem. But that had no impact.
The Targeted Device Families are iPhone and iPad only, and I have toggled the iOS Deployment Target from 10.0 through 14.0, and that hasn't changed anything, either.
And cmd-F'ing "LSApplicationLaunchProhibited" isn't finding anything I can switch to false to test that.
Bottom line: Simple sticker pack, no code, shouldn't be generating a 32 bit version of anything and shouldn't be messing around with Mac Apple Silicon issues, and yet here we are.
First time here, so thanks for obliging these newbie questions!
Side note: It is a similar question to this one, but going in the opposite direction, so I thought posting a potentially duplicate question was in order:
