UserNotifications Framework - Push Notification In iOS 10 Swift 3.0

Apple introduced new framework UserNotifications.framework ^[1] for delivery and handling of local and remote notification. The UserNotifications framework supported iOS 10.0 + , tvOS 10.0 + , and watchOS 3.0+.

We are discussing only about the code for notification. Here the code for both iOS 10+ and also below of iOS version in Swift 3.0.

Step 1 : Import UserNotifications framework in your AppDelegate file for iOS 10.

  import UserNotifications

Step 2 : Add UNUserNotificationCenterDelegate in AppDelegate.

  class AppDelegate: UIResponder, UIApplicationDelegate , UNUserNotificationCenterDelegate{

Step 3 : To register local or remote notification, Add the code in didFinishLaunch delegate method.

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions:      [UIApplicationLaunchOptionsKey: Any]?) -> Bool {      if #available(iOS 10.0, *) {          let center = UNUserNotificationCenter.current()          center.delegate = self          center.requestAuthorization(options: [UNAuthorizationOptions.sound ], completionHandler: { (granted, error) in              if error == nil{                  UIApplication.shared.registerForRemoteNotifications()              }          })      } else {          let settings  = UIUserNotificationSettings(types: [UIUserNotificationType.alert , UIUserNotificationType.badge , UIUserNotificationType.sound], categories: nil)          UIApplication.shared.registerUserNotificationSettings(settings)          application.registerForRemoteNotifications()      }      return true  }

Step 4: Now the Local and Remote notification response is Handle by its delegate method. When You are working iOS 10 or later, then notification response handle in UNUserNotificationDelegate methods.

  @available(iOS 10.0, *)  func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {      print("User Info === \(notification.request.content.userInfo)")      // Handle code here.      completionHandler([UNNotificationPresentationOptions.sound , UNNotificationPresentationOptions.alert , UNNotificationPresentationOptions.badge])  }    @available(iOS 10.0, *)  func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {      print("User Info === \(response.notification.request.content.userInfo)")      completionHandler()  }

Step 5: Below iOS 10, Local and Remote notification response is Handle by its Application delegate method.

  func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {      let characterSet = CharacterSet(charactersIn: "<>")      let deviceTokenString: String = ((deviceToken.description as NSString).trimmingCharacters(in: characterSet) as NSString).replacingOccurrences(of: " ", wi   th: "") as String      print(deviceTokenString)  }    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {      print(userInfo)  }  func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {      print(error.localizedDescription)  }
