title: iOS 13 Dark theme settings in app don't change alert controller call phone number style
body: <p>In my app, I want use only light mode. In AppDelegate didFinishLaunchingWithOptions I use:</p>
  
  <pre><code>if #available(iOS 13.0, *) {
               UIWindow.appearance().overrideUserInterfaceStyle = .light
           }
  </code></pre>
  
  <p>and it work well. But when I use:</p>
  
  <pre><code>  if let url = URL(string: "tel://\(alertItems[indexPath.row - 1].phoneNumber)"), UIApplication.shared.canOpenURL(url) {
      UIApplication.shared.open(url)
  </code></pre>
  
  <p>alert controller appears with system settings theme (dark for example).
  How I can solve this problem? </p>
