# Best practices for migrating from UILocalNotification to User Notifications framework

# UserNotifications

  • You will have to import UserNotifications
     @import UserNotifications;
  • 2.Request authorization for localNotification

    let center = UNUserNotificationCenter.current()
    center.requestAuthorization([.alert, .sound]) { (granted, error) in
        // Enable or disable features based on authorization.
  • Now we will update the application icon badge number
     @IBAction  func triggerNotification(){
     let content = UNMutableNotificationContent()
     content.title = NSString.localizedUserNotificationString(forKey: "Tom said:", arguments: nil)
     content.body = NSString.localizedUserNotificationString(forKey: "Hello Mike!Let's go.", arguments: nil)
     content.sound = UNNotificationSound.default()
     content.badge = UIApplication.shared().applicationIconBadgeNumber + 1;
     content.categoryIdentifier = "com.mike.localNotification"
     //Deliver the notification in two seconds.
     let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 1.0, repeats: true)
     let request = UNNotificationRequest.init(identifier: "TwoSecond", content: content, trigger: trigger)
     //Schedule the notification.
     let center = UNUserNotificationCenter.current()
     @IBAction func stopNotification(_ sender: AnyObject) {
     let center = UNUserNotificationCenter.current()
