iOS Application Register for Apple Push Notification

Following function will help you to registering for Push notification on an iOS Application.

func registerForNotification(_ application: UIApplication) {
	if #available(iOS 10.0, *) {
		let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
			options: authOptions,
			completionHandler: { _, _ in }
		// For iOS 10 display notification (sent via APNS)
		UNUserNotificationCenter.current().delegate = self
	} else {
		let setting = UIUserNotificationSettings(
			types: [.alert, .badge, .sound], 
			categories: nil

Step 1. Copy and Paste above function and place it under AppDelegate.swift file of your project.

Step 2. Now under method, make sure you invoke above method.

func application(_ application: UIApplication, didFinishLaunchingWithOptions 
			launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
	// Register for push notification
	// Override point for customization after application launch.
	return true

Step 3. Also add following delegate methods to AppDelegate.swift

func application(_ application: UIApplication, 
		didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
	print("Need something to be done when success registring for APNS ")	
func application(_ application: UIApplication, 
	didFailToRegisterForRemoteNotificationsWithError error: Error) {
	print("Need something to be done when registring for APNS fails")		

Step 4. Make sure that you’ve enabled Push notification settings from Target Settings.
