Deprecations

Don’t use the iOS MinimumOSVersion information property list key to declare the minimum release of macOS in which your app runs. Use LSMinimumSystemVersion instead. (73890473)
- Future releases of macOS ignore the MinimumOSVersion key in Mac apps, including apps built with Mac Catalyst.
- Future releases of macOS use the LSMinimumSystemVersion key in iOS apps built with Xcode 12.5 or later. If an iOS app doesn’t include an LSMinimumSystemVersion key, future releases of macOS compare the app’s MinimumOSVersion with the version of its Mac Catalyst runtime to determine compatibility.
