@available(iOS 13.0, *)
func changeMode() {

      let alertController = UIAlertController(title: nil, message: nil, preferredStyle: .alert)
          alertController.addAction(UIAlertAction(title: "DARK MODE", style: .default, handler: { action in

           UIWindow.animate(withDuration: 0.5, animations: {
                 UIApplication.shared.keyWindow?.overrideUserInterfaceStyle = .dark
                //also try : UIApplication.shared.windows.last?.overrideUserInterfaceStyle = .dark
                })
         }))

          alertController.addAction(UIAlertAction(title: "LIGHT MODE", style: .default, handler: { action in

           UIWindow.animate(withDuration: 0.5, animations: {
                 UIApplication.shared.keyWindow?.overrideUserInterfaceStyle = .light
                 //UIApplication.shared.windows.last?.overrideUserInterfaceStyle = .light

                })

          }))

    self.present(alertController, animated : true)

}

Thank you very much, but can you help with animations, because this code makes changing very quickly and sharply. – Аба-Бакри Ибрагимов Dec 23 '19 at 03:23
I tried this solution, but iOS animations are different. For example when I want to change iOS mode in settings it's working very smoothly and beautiful . where I can find this solution ? – Аба-Бакри Ибрагимов Dec 23 '19 at 08:43
You will have to animate the current presented view controller. – Celeste Dec 23 '19 at 10:37
