Clicking the Firebase dynamic link does not call the application (_: continue: restorationHandler :) method in AppDelegate

Using Firebase Dynamic Links, I want to be able to click a link to open an iOS app.

The app is under development and is not yet on the AppStore.

I set it while looking at the document, but even if the app is started by clicking the link, the application (_: continue: restorationHandler :) method in AppDelegate is not called.

I set it according to the following procedure. Is something wrong? 　

  1. Add "pod 'Firebase / DynamicLinks'" to Podfile and install

  2. Open the .xcworkspace file

  3. Create Dynamic Links “https://XXXX.page.link/test”

  4. Access “https://XXXX.page.link/apple-app-site-association”

    {"applinks":{"apps":[],"details":[{"appID":"XXXXXXX.[Bundle ID]","paths":["NOT /_/","/"]}]}}

  5. Create a URL type to use for dynamic links enter image description here

  6. Enable "Associated Domains" and add "applinks: XXXX.page.link" enter image description here

  7. Implement AppDelegate as below

    import UIKit
import Firebase
import FirebaseDynamicLinks

@UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        FirebaseApp.configure()
        return true
    }

    // MARK: UISceneSession Lifecycle

    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
        // Called when a new scene session is being created.
        // Use this method to select a configuration to create the new scene with.
        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
    }

    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
        // Called when the user discards a scene session.
        // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
        // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
    }

    func application(_ application: UIApplication, continue userActivity: NSUserActivity,
                 restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
      let handled = DynamicLinks.dynamicLinks().handleUniversalLink(userActivity.webpageURL!) { (dynamiclink, error) in
        // ...
      }

      return handled
    }

    @available(iOS 9.0, *)
    func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
      return application(app, open: url,
                     sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
                     annotation: "")
    }

    func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
      if let dynamicLink = DynamicLinks.dynamicLinks().dynamicLink(fromCustomSchemeURL: url) {
        // Handle the deep link. For example, show the deep-linked content or
        // apply a promotional offer to the user's account.
        // ...
        return true
      }
      return false
    }
}

I was calling the scene method of SceneDelegate.

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
        // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
        // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).

        // Create the SwiftUI view that provides the window contents.
        let rootView = ContentView()

        // Use a UIHostingController as window root view controller.
        if let windowScene = scene as? UIWindowScene {
            let window = UIWindow(windowScene: windowScene)
            window.rootViewController = UIHostingController(rootView: rootView)
            self.window = window
            window.makeKeyAndVisible()
        }

        guard let userActivity = connectionOptions.userActivities.first(where: { $0.webpageURL != nil }) else { return }
        print("url: \(userActivity.webpageURL!)")
    }

    func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
        print("url: \(userActivity.webpageURL!)") 
    }
    ...
}

Implementation should be in SceneDelgate instead of AppDelegate
