I've already added AppIcon.appiconset Icon Files in info.plist, also no xcassets warnings. If I understand correctly, the app should show AppIcon if I set IconFiles in info.plist and AppIcons in General right?

Turns out it's a bug in Xcode 13 lol. Restarting my Mac solved the problem. https://developer.apple.com/forums/thread/682648
