Alarm in iOS Swift

-


In iOS, we don't have Alarm manager.But we will use local notification as an alarm manager.
We will play the sound as like alarm.
Code:
        let notification = UILocalNotification()
        notification.soundName = "alarm.mp3" // add soundfile to your project and put the name here
        notification.timeZone = NSTimeZone.local
        notification.userInfo = data as? [String: AnyObject] //set the notification data here and get and process in the receiving end
        notification.fireDate = NsDate()  // set the alarm time
        UIApplication.shared.scheduleLocalNotification(notification)   // fire the notification
