I'm trying to change app icon on Dock in macOS from my app. But couldn't get to work. The setAlternateIconName works fine in iOS simulator, but when I run in on my mac (Catalyst) I got this error: The requested operation couldn’t be completed because the feature is not supported.
Apple Doc - https://developer.apple.com/documentation/uikit/uiapplication/2806818-setalternateiconname
Thank you
