iOS 13 window background color

Question

The image above is in dark mode, with the following setup in the app delegate:

if (@available(iOS 13.0, *)) {
    self.window.backgroundColor = [UIColor systemBackgroundColor];
}

The problem is that the top white should be black in dark mode.
How can I make that happen?

Thanks.

In iOS 13 the window belongs to the scene delegate, not the app delegate. — matt, Aug 29 '19 at 14:46
@matt interesting.. I do have a valid window object though in the app delegate: ` — Zsolt, Aug 29 '19 at 15:38
@Zsolt Did you finally find the solution? I am getting the same problem here. — Zigii Wong, Jul 06 '20 at 03:59

Is it still the issue? Here is my code which redirect to initialViewController based on login status. And it is working.

if let appDelegate = UIApplication.shared.delegate as? AppDelegate {
    appDelegate.window?.rootViewController = initialViewController
    appDelegate.window?.makeKeyAndVisible()

    if #available(iOS 13.0, *) {
         appDelegate.window?.backgroundColor = .systemBackground
    }else{
         appDelegate.window?.backgroundColor = .white // as you want
    }
 }
