Device Token not received when registering for remote notifications in Swift

Question

I somehow can not receive the device token when registering for remote notifications. I get the modal saying "Do you want to allow App X to be able to send you notificaitons", but when I accept it, the didRegisterForRemoteNotifications function is not called.

When I register for remote notifications in iOS 8/Swift using this code:

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

These functions are not triggered at all:

   func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData!) 

and

func application(application: UIApplication,    didFailToRegisterForRemoteNotificationsWithError error: NSError!) 

however when I log this

println("current settings \(UIApplication.sharedApplication().currentUserNotificationSettings()) and \(UIApplication.sharedApplication().isRegisteredForRemoteNotifications())")

I receive

"current settings <UIUserNotificationSettings: 0x170437120; types: (UIUserNotificationTypeAlert UIUserNotificationTypeBadge UIUserNotificationTypeSound);> and true" 

My provisioning profile and certificates ar all in order.

Has someone else had this problem?

For swift 4.0 please follow some steps :

1).On push notification in capabilities(TARGET)

2).Use this code in didFinishLaunchingWithOptions

  let settings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)

        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()

3).Add this also

 func application(_ application: UIApplication,
                 didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let tokenParts = deviceToken.map { data -> String in
        return String(format: "%02.2hhx", data)
    }

    let token = tokenParts.joined()
    print("Device Token: \(token)")  
}

You can try this

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        var types: UIUserNotificationType = UIUserNotificationType.Badge |
            UIUserNotificationType.Alert |
            UIUserNotificationType.Sound

        var settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)

        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()

        return true
    }

    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {

        var characterSet: NSCharacterSet = NSCharacterSet(charactersInString: "<>")

        var deviceTokenString: String = (deviceToken.description as NSString)
            .stringByTrimmingCharactersInSet(characterSet)
            .stringByReplacingOccurrencesOfString( " ", withString: "") as String

        println(deviceTokenString)

    }

EDIT: Update for Swift 2.x

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.


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

        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()

        return true
    }

EDIT: Update for Swift 3.x

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

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

    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()

    return true
}


func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
let characterSet = CharacterSet(charactersIn: "<>")
    let deviceTokenString = deviceToken.description.trimmingCharacters(in: characterSet).replacingOccurrences(of: " ", with: "");
    print(deviceTokenString)
}
