    var window: UIWindow?

    lazy var appRemote: SPTAppRemote = {

        guard let url = URLContexts.first?.url else {
            return
        }

        let parameters = appRemote.authorizationParameters(from: url);

        if let access_token = parameters?[SPTAppRemoteAccessTokenKey] {

            // Show the error
        }

    }

    func sceneDidBecomeActive(_ scene: UIScene) {
        connect();
    }

    func sceneWillResignActive(_ scene: UIScene) {
        playerViewController.appRemoteDisconnect()
        appRemote.disconnect()
    }

    func connect() {
        playerViewController.appRemoteConnecting()
        appRemote.connect()
    }

    // MARK: AppRemoteDelegate

    func appRemoteDidEstablishConnection(_ appRemote: SPTAppRemote) {
        self.appRemote = appRemote
        playerViewController.appRemoteConnected()
    }

    func appRemote(_ appRemote: SPTAppRemote, didFailConnectionAttemptWithError error: Error?) {
        print("didFailConnectionAttemptWithError")
        playerViewController.appRemoteDisconnect()
    }

    func appRemote(_ appRemote: SPTAppRemote, didDisconnectWithError error: Error?) {
        print("didDisconnectWithError")
        playerViewController.appRemoteDisconnect()
    }

    var playerViewController: ViewController {
        get {
            let navController = self.window?.rootViewController?.children[0] as! UINavigationController
            return navController.topViewController as! ViewController
        }
    }


}

Does anyone know how to implement this on a specific view controller after everything is done on the Scene delegate?
