Declaring let navigationBarAppearace = UINavigationBar.appearance() navigationBarAppearace.titleTextAttributes = [NSAttributedString.Key.foregroundColor:UIColor.white] navigationBarAppearace.backgroundColor = UIColor.blue did the trick. However, I'm now trying to change this area's color:

Here IOS 15.4, Xcode 13.2.1 and I still get this error over and over again. It started when I upgraded Iphone's 12 Pro Max to IOS to 15.4. Already restarted both, MacBook and iPhone 12 Pro Max several times e nothing seems to get it to work. Mac Book has BigSur 11.6.5 I have another iPhone 7 with 15.3.1 where the error does not happen. Any help?
