How to set up push notifications in Swift

Question

I am trying to set up a push notification system for my application. I have a server and a developer license to set up the push notification service.

I am currently running my app in Swift. I would like to be able to send the notifications remotely from my server. How can I do this?

Answer 1

Swift 2:

let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil) UIApplication.sharedApplication().registerUserNotificationSettings(settings) UIApplication.sharedApplication().registerForRemoteNotifications() 

Answer 2

While the answer is given well to handle push notification, still I believe to share integrated complete case at once to ease:

To Register Application for APNS, (Include the following code in didFinishLaunchingWithOptions method inside AppDelegate.swift)

---

IOS 9

var settings : UIUserNotificationSettings = UIUserNotificationSettings(forTypes:UIUserNotificationType.Alert|UIUserNotificationType.Sound, categories: nil) UIApplication.sharedApplication().registerUserNotificationSettings(settings) UIApplication.sharedApplication().registerForRemoteNotifications() 

---

After IOS 10

Introduced UserNotifications framework:

Import the UserNotifications framework and add the UNUserNotificationCenterDelegate in AppDelegate.swift

---

To Register Application for APNS

let center = UNUserNotificationCenter.current() center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in      // If granted comes true you can enabled features based on authorization.     guard granted else { return }      application.registerForRemoteNotifications() } 

This will call following delegate method

func application(application: UIApplication,didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) { //send this device token to server }  //Called if unable to register for APNS. func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {  println(error)  } 

On Receiving notification following delegate will call:

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {      println("Recived: \(userInfo)")    //Parsing userinfo:    var temp : NSDictionary = userInfo    if let info = userInfo["aps"] as? Dictionary<String, AnyObject>              {                 var alertMsg = info["alert"] as! String                 var alert: UIAlertView!                 alert = UIAlertView(title: "", message: alertMsg, delegate: nil, cancelButtonTitle: "OK")                 alert.show()             } } 

To be identify the permission given we can use:

UNUserNotificationCenter.current().getNotificationSettings(){ (setttings) in          switch setttings.soundSetting{         case .enabled:             print("enabled sound")          case .disabled:             print("not allowed notifications")          case .notSupported:             print("something went wrong here")         }     }

So the checklist of APNS:

• Create AppId allowed with Push Notification
• Create SSL certificate with valid certificate and app id
• Create Provisioning profile with same certificate and make sure to add device in case of sandboxing(development provisioning)

Note: That will be good if Create Provisioning profile after SSL Certificate.

With Code:

• Register app for push notification
• Handle didRegisterForRemoteNotificationsWithDeviceToken method
• Set targets> Capability> background modes> Remote Notification
• Handle didReceiveRemoteNotification
