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?

1) create push notification and attach with your profile 2) on in capabilities push notification 3) Send device token see more to down my answer is there — Hardik Bar, Oct 07 '16 at 12:19

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)
}

Still doesn't work! Could it have something to do with a certificate? — Samuel B., May 11 '15 at 14:12
"http://stackoverflow.com/questions/33970840/device-token-not-received-on-ipad" could you able to find answer for this question I tried with your answers but it doesn't work for iPad — satheesh, Nov 28 '15 at 12:08
what are you doing different from the OP's code? What's wrong with doing : `UIApplication.sharedApplication()`? — mfaani, Feb 16 '17 at 23:40

For Swift 3.0 you can use:

let deviceTokenString = message.reduce("", {$0 + String(format: "%02X", $1)})

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)")  
}

Please make sure your certificates are valid and app is registered successfully,Do some Googling and u will sure find right way.This code worked for me.

(in AppDelegate.swift didFinishLaunchingWithOptions method )

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

// Add Delegate methods of UIApplication

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

    println("\(deviceToken)")
}

//Called if unable to register for APNS.

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

    println(error)

}

For Swift 5, I have used like this,

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

    UIApplication.shared.registerForRemoteNotifications()

it is deprecated in ios10, use requestAuthorization method of UNUserNotificationCenter now. – Harish Pathak Feb 21 '23 at 10:15

If you get this message, then you have already registered and the method will get called only when the application gets launched or the token gets changed. It has slight chance that the token will be updated.

Probably, you can try to delete the application from you test device and try to clear it from Xcode. And do it over again.

Thanks for you answer, but I already tried that and tried it on multiple devices. – Samuel B. May 05 '15 at 15:33

When didRegisterForRemoteNotificationsWithDeviceToken doesn't get called, you should always first reconnect to another Wi-Fi network, or toggle Flight modus twice, and restart your app, before you try anything else. Otherwise restarting your device may also help.
