iOS 13 > Universal App Links does not work when app is killed and not in background

Question

Any idea why starting from iOS 13 app links (universal links) this defines via Apple-App-Site-Association stopped working?

I have 2 implementations in ApplicationDelegate and in SceneDelegate. Now works only implementation in SceneDelegate and only if application is in background, if I kill app then method continueUserActivity isn't called. I have added Haptic Feedback to track this method call but it will never be invoked neither in ActivityDelegate or SceneDelegate.

// MARK: - Universal Links support
extension SceneDelegate {

    func scene(_ scene: UIScene, willContinueUserActivityWithType userActivityType: String) {
        print("[Scene] Will continue user activity: ", userActivityType)
        let generator = UINotificationFeedbackGenerator()
        generator.notificationOccurred(.success)

    }

    func scene(_ scene: UIScene, didFailToContinueUserActivityWithType userActivityType: String, error: Error) {
        print("[Scene] Did fail to continue user activity: ", userActivityType)
    }

    func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {

        print("[Scene] Application continue user activity...")

        if userActivity.activityType == NSUserActivityTypeBrowsingWeb {
            if let url = userActivity.webpageURL {
                if !present(url: url) { UIApplication.shared.open(url, options: [:]) }
            }
        }
    }

And Application Delegate case

// MARK: - Universal Links support
extension AppDelegate {

    func application(_ application: UIApplication, willContinueUserActivityWithType userActivityType: String) -> Bool {
        print("[App] Will continue user activity: ", userActivityType)
        let generator = UINotificationFeedbackGenerator()
        generator.notificationOccurred(.warning)
        return true
    }

    func application(_ application: UIApplication, didFailToContinueUserActivityWithType userActivityType: String, error: Error) {
        print("[App] Did fail to continue user activity: ", userActivityType)
    }

    func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {

        print("[App] Application continue user activity...")

        if userActivity.activityType == NSUserActivityTypeBrowsingWeb {
            if let url = userActivity.webpageURL {
                if !present(url: url) { UIApplication.shared.open(url, options: [:]) }
            }
        }
        return true
    }

App is being opened but the methods are not called and I cannot navigate to appropriate screen inside my app.

Ok I've found it you must do something like this

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
   
    if let userActivity = connectionOptions.userActivities.first {
      self.scene(scene, continue: userActivity)
    }
  }
