Notifications aren't displaying with Firebase

Question

So I just implemented (well attempted to) Push Notifications for my app. I have sorted all the certificates out and have everything running within Xcode. I uploaded my .p12 file to Firebase in the development section and even downloaded the provisioning profile and reinstalled it into my project.

This is the code in my AppDelegate.swift file

Updated code:

import UIKit
import Firebase
import FirebaseMessaging

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
    var storyboard: UIStoryboard?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        FIRApp.configure()

        // Override point for customization after application launch.

        self.storyboard =  UIStoryboard(name: "Main", bundle: NSBundle.mainBundle())
        let currentUser = FIRAuth.auth()?.currentUser
        if currentUser != nil
        {
            self.window?.rootViewController = self.storyboard?.instantiateViewControllerWithIdentifier("tBVC")
        }
        else
        {
            self.window?.rootViewController = self.storyboard?.instantiateViewControllerWithIdentifier("loginScreen")
        }

        return true
    }

    func registerForPushNotifications(application: UIApplication) {
        let notificationSettings = UIUserNotificationSettings(
            forTypes: [.Badge, .Sound, .Alert], categories: nil)
        application.registerUserNotificationSettings(notificationSettings)
    }

    func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
        if notificationSettings.types != .None {
            application.registerForRemoteNotifications()
        }
    }

    func applicationWillResignActive(application: UIApplication) {
        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
        // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
    }

    func applicationDidEnterBackground(application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    }

    func applicationWillEnterForeground(application: UIApplication) {
        // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
    }

    func applicationDidBecomeActive(application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    }

    func applicationWillTerminate(application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    }

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

        print(userInfo)
        print("MessageID:  \(userInfo["gcm_message_id"]!)")
        //
    }


}

When the app is running in the background no notifications display, even when my device is locked still nothing. The alert popped up asking if the app had permission to send notifications and I said yes.

I followed this tutorial

Any idea why my notifications aren't being displayed? In the Firebase Console it says that the status of the notification is 'Completed'

EDIT - Added image of my capabilities in Xcode

Answer 1

I worked out the reason for why it was doing so! As @Collinizer stated there were issues with Apple and there APNS but it is all working now! I added push notifications in using OneSignal and they are working like a dream!

Thank you to all that helped :)

You need to configure set up of APNS device token which is crucial to push notifications with Firebase Cloud Messaging (FCM).

First let's back up a little bit and start by just seeing if we can at least get token success.

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

FIRApp.configure()
return true
}

func registerForPushNotifications(application: UIApplication) {
    let notificationSettings = UIUserNotificationSettings(
        forTypes: [.Badge, .Sound, .Alert], categories: nil)
    application.registerUserNotificationSettings(notificationSettings)
}

func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
    if notificationSettings.types != .None {
        application.registerForRemoteNotifications()
    }
}


func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
var tokenString = ""

for i in 0..<deviceToken.length {
    tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
}


FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Unknown)
print("Device Token:", tokenString)
}
