Globally change the appearance of the application

by iOS Example

About

I tried to create a project where you can globally change the appearance of the application. Perhaps someone was looking for such a solution.

⭐️ Put a like if I helped you, and write ideas on what can be done better.

Themes

  • .unspecified The appearance of the system is used.
  • .light Permanent light appearance.
  • .dark Permanent dark appearance.

Colors

  • .red .pink .orange .yellow .green .blue .purple
  • Your own colors that you like.
SceneDelegate

    func scene(_ scene: UIScene, 
               willConnectTo session: UISceneSession,
               options connectionOptions: UIScene.ConnectionOptions) {
        self.window?.overrideUserInterfaceStyle = ThemeService.shared.theme.getUserInterfaceStyle()
        self.window?.tintColor = ColorService.shared.color.getColorStyle()
    }
AppDelegate

    func application(_ application: UIApplication, 
                     didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        if UserDefaults.standard.object(forKey: DefaultKeys.switchState) == nil {
            UserDefaults.standard.set(true, forKey: DefaultKeys.switchState)
        }
        if UserDefaults.standard.object(forKey: DefaultKeys.selectedColor) == nil {
            UserDefaults.standard.set(5, forKey: DefaultKeys.selectedColor)
        }
        return true
    }
