        super.viewDidLoad()

        // Configure User Notification Center

            UNUserNotificationCenter.current().delegate = self

    }

Step 3:

@IBAction func didLocalNotification(_ sender: Any) {

        // Request to notification settings

        UNUserNotificationCenter.current().getNotificationSettings { (notificationSettings) in

            switch notificationSettings.authorizationStatus {

                case .notDetermined:

                    self.requestAuthorization(completionHandler: { (success) in

                        guard success else { return }

                        self.getScheduleLocalNotification()  // Schedule Local Notification

                    })

                    // Request Authorization

Step 4: // Request For Authorization

 

private func requestAuthorization(completionHandler: @escaping (_ success: Bool) -> ()) {

        // Request Authorization

        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (success, error) in

            if let error = error {
