How to implement local notification in Swift

• Mac
• Xcode6 - BetaX
• iOS8

Steps

1. Open xcode.
2. Create a Single View Application, let's name it LocalNotification.
3. Register for user notification.
1. In the newly created project, open AppDelegate.swift
2. Insert the lines below in: didFinishLaunchingWithOptions

application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert |
            UIUserNotificationType.Badge, categories: nil
            ))

4. To show an alert view when we received a local notification, we need to override: didReceiveLocalNotification,

func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
 print("received local notification")
 
 application.applicationIconBadgeNumber = 0
 
 var alert = UIAlertView()
 alert.title = "Alert"
 alert.message = notification.alertBody
 alert.addButtonWithTitle("Dismiss")
 
 alert.show()
}

5. To demo local push notification in our app, we override ViewController.swift viewDidLoad method. So open this file and paste the lines below:

override func viewDidLoad() {
 super.viewDidLoad()
 // Do any additional setup after loading the view, typically from a nib.
 
 var localNotification = UILocalNotification()
 localNotification.fireDate = NSDate(timeIntervalSinceNow: 30)
 localNotification.alertBody = "Hello World"
 localNotification.timeZone = NSTimeZone.defaultTimeZone()
 localNotification.applicationIconBadgeNumber = 1

        //play a sound
 localNotification.soundName = UILocalNotificationDefaultSoundName;
 localNotification.alertAction = "View"
 
 UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
}

6. To test if our app works, open the app and let it open the view. Then open another app, or just hide our app. After 30 seconds you should received a push notification alert.
7. Note that local notification only works on real iPhone device.
