I am trying to make a VERY simple PUSH from a remote server to an app.

I have set up a notification hub on Azure as per [1], but I cannot get a debug message down to the device. **I DO NOT WANT TO READ / WRITE FROM A DB TABLE USING MOBILE SERVICES** 

I am doing this in Swift, and I have found **nothing** on the internet that actually receives a push from a server is iOS swift as a complete tutorial.

I do not know, for example, how to write the following code in swift:

```
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // TODO: update @"MobileServiceUrl" and @"AppKey" placeholders
    MSClient *client = [MSClient clientWithApplicationURLString:@"MobileServiceUrl" applicationKey:@"AppKey"];

    [client.push registerNativeWithDeviceToken:deviceToken tags:@[@"uniqueTag"] completion:^(NSError *error) {
        if (error != nil) {
            NSLog(@"Error registering for notifications: %@", error);
        }
    }];
}

```

So far this is my code in my AppDelegate (some of the code I got from [2]):

```
    var client: MSClient?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    if(UIApplication.instancesRespondToSelector(Selector("registerUserNotificationSettings:")))
    {
        application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge, categories: nil))
    }
    /*else
    {
    //do ios7 stuff here. If you are using just local notifications then you dont need to do anything. for remote notifications:
    application.registerForRemoteNotificationTypes(UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge)
    }*/

    self.client = MSClient(applicationURLString: "[url]", applicationKey: "[key]")

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

    return true
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    println("Got device token \(deviceToken)");
    //IS THIS EVEN CORRECT???? [3] and [4]
    /*let json = ("{\"platform\":\"ios\", \"deviceToken\":\"\(deviceToken)\"}" as NSString).dataUsingEncoding(NSUTF8StringEncoding)

    self.client?.invokeAPI("register_notifications", data: json, HTTPMethod: "POST", parameters: nil, headers: nil, completion:nil)*/
    let registrationTags: [String] = ["tag"];
    //EDIT 1 - I HAVE MADE A LITTLE PROGRESS
    self.client?.push.registerNativeWithDeviceToken(deviceToken, tags: registrationTags, completion: { (error) -> Void in
        println("Error registering")
    })
}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    println("Could not register \(error)");
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    println("Remote notification received!")
    println("Awesome!")
}

```

I am getting a device token back, which means I should be registered, but I do not know how to properly implement [code]

```
self.client?.push.registerNativeWithDeviceToken(deviceToken: deviceToken, tags: registrationTags, completion: [code])

```

**EDIT 1** I have made some progress here:

```
self.client?.push.registerNativeWithDeviceToken(deviceToken, tags: registrationTags, completion: { (error) -> Void in
        println("Error registering")
    })

```

Now I get an error with registering:

>

>  } }, com.Microsoft.WindowsAzureMobileServices.ErrorRequestKey= { URL: <https://[servicename].azure-mobile.net/push/registrations%3FdeviceId=[longnumber]&platform=apns> }}

**EDIT 2**

I have now made the following changes after reading [5]:

```
    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
        let token = NSString(data: deviceToken, encoding: NSUTF8StringEncoding)
        println("Got device token");        

        let hub = SBNotificationHub(connectionString: CONNECTIONSTRING, notificationHubPath: HUBPATH)
        hub.registerNativeWithDeviceToken(deviceToken, tags: nil, completion: {(error) -> Void in
            println("Error registering: \(error)")
        })
    }

```

And the output I now see is:

> 
> Got device token  
> 
>  Error registering: nil
> 
> 
> 

I feel like I am making progress but when I send the debug push from Azure I see nothing in my logs (currently when I receive a push I just print a message)
