The closest I’ve come is dragging the .app bundle (from the .ipa file generated by Solar2D) on the running simulator, but the sim complains:
“The Info.plist in the bundle at /Users/john_carlson/Library/Developer/CoreSimulator/Devices/C5B16149-036E-4813-9EA7-2FF6E11006BD/data/Library/Caches/com.apple.mobile.installd.staging/temp.Y8FoI5/extracted/Queue Alert.app declares UIDeviceFamily specifying compatibility with iOS and/or iPadOS but the bundle’s executable does not contain a slice built for either iOS or iPadOS. Update the declaration of UIDeviceFamily in the Info.plist to match the platform for which this bundle is built.”
