This can be done by adding an macOS plugin which has access to the whole AppKit API.  Then you can set the desired appearance there at runtime, for example: NSApplication.shared.appearance = NSAppearance(named: .darkAqua) For more information please see this StackOverflow question: How to set dark mode for NSToolbar in macOS Catalyst app?

I have exactly the same problem - although all information in the .plist file and the localized InfoPlist.strings files is there, my app gets rejected and I don't know how to reproduce the issue. Does anybody knows a solution for this?

I have the same problem - what is service name for resetting the location permissions in macOS 11.1? Is there a list with all the available service names?

Thanks - yes, exactly this is the problem here, the crash appears only for alerts with no actions. I use them for progress messages which disappear automatically if the work is completed.Adding a 'dummy' action fixes the crash, but to make the alert disappear you have to press this button.Calling [UIViewController dismissViewControllerAnimated:completion:] executes the completion code,but does not hide the alert.Is there a solution without this dummy button?Is it possible to use the NSAlert from AppKit directly here in an UIKitForMac app?
