Answer 1

To support ios 8 and before, use this:

// Register for Push Notitications, if running iOS 8
if application.respondsToSelector("registerUserNotificationSettings:") {

  let types:UIUserNotificationType = (.Alert | .Badge | .Sound)
  let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)

  application.registerUserNotificationSettings(settings)
  application.registerForRemoteNotifications()

} else {      
  // Register for Push Notifications before iOS 8
  application.registerForRemoteNotificationTypes(.Alert | .Badge | .Sound)
}

I use this code snip in AppDelegate.swift:

let pushType = UIUserNotificationType.alert.union(.badge).union(.sound)
let pushSettings = UIUserNotificationSettings(types: pushType
            , categories: nil)

application.registerUserNotificationSettings(pushSettings)
application.registerForRemoteNotifications()

Swift 2:

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

Swift 4

Import the UserNotifications framework and add the UNUserNotificationCenterDelegate in AppDelegate

import UserNotifications

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate

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

let center = UNUserNotificationCenter.current()
    center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
        // Enable or disable features based on authorization.
    }
    application.registerForRemoteNotifications()

This will call following delegate method

func application(_ application: UIApplication,didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    //send this device token to server

}

//Called if unable to register for APNS.
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    print(error)
}

On Receiving notification following delegate will call:

private func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {

    print("Recived: \(userInfo)")
    //Parsing userinfo:

}

You can send notification using the following code snippet:

let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
if(UIApplication.sharedApplication().currentUserNotificationSettings() == settings ){
//OK
}else{
//KO
}
