How to Add Local Push Notification With timeInterval & Test On Simulator

  1. In Project Target ( Signing & Capapilities ) Add Capapility :

    1. Background Modes : Check -> [ Bachground fetch , Remote notifications , Background processing ]
    
    2. Push Notification
    

//———————————————————————————————

  1. In App Delegate Import :

    import UserNotifications
    
    import BackgroundTasks
    

//———————————————————————————————

  1. Add Settings of Push Notification ->

|. Define gcmMessageIDKey :

    let gcmMessageIDKey = "gcm.message_id"

||. Add Delegate of UNUserNotificationCenterDelegate for handle message :

    // [START ios_10_message_handling]
    @available(iOS 10, *)
    extension AppDelegate : UNUserNotificationCenterDelegate {

        func userNotificationCenter(_ center: UNUserNotificationCenter,
                            willPresent notification: UNNotification,
                            withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

            let userInfo = notification.request.content.userInfo

            if let messageID = userInfo[gcmMessageIDKey] {
                print("Message ID: \(messageID)")
            }

            completionHandler([.alert,.badge, .sound])

            print(userInfo)

        }

        func userNotificationCenter(_ center: UNUserNotificationCenter,
                            didReceive response: UNNotificationResponse,
                            withCompletionHandler completionHandler: @escaping () -> Void) {
            let userInfo = response.notification.request.content.userInfo

            print(userInfo)

            completionHandler()
        }
      }

//———————————————————————————————

  1. In App Delegate add method :

    func applicationDidEnterBackground(_ application: UIApplication) {
        application.beginBackgroundTask {} // Allows to run background tasks
    }
    

//———————————————————————————————

  1. In App Delegate Inside method didFinishLaunchingWithOptions add :

    application.beginBackgroundTask(withName: "showNotification", expirationHandler: nil)
    
    let center = UNUserNotificationCenter.current()
    
    center.delegate = self as! UNUserNotificationCenterDelegate
    

//———————————————————————————————

  1. Call this method to take a permission for use push notification :

    func TakeLocalNotificationPermisiion(){
       UNUserNotificationCenter.current().requestAuthorization(options: [.alert , .badge , .sound]) { (granted, error) in
          if granted {
              print("User gave permissions for local Notifications")
          }else{ 
    
          }
      }
      }
    

//———————————————————————————————

  1. You Can Test By The following lines :

     let content = UNMutableNotificationContent()
     
     content.title = "Technicalisto"
     
     content.subtitle = "Test Local Push Notification On Simulator"
     
     content.sound = UNNotificationSound.default
    
     let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 1, repeats: false)
    
     let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
    
     UNUserNotificationCenter.current().add(request)
