Firebase - Swift 4: Message sent but not received - swift

Question

Ran pod update on the terminal to update my firebase. However i don't receive FCM's
This is my app delegate code:
import UIKit
import Firebase
import FirebaseFirestore
import StoreKit
import UserNotifications
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate {
var window: UIWindow?
override init() {
super.init()
FirebaseApp.configure()
// not really needed unless you really need it FIRDatabase.database().persistenceEnabled = true
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
Auth.auth().signInAnonymously() { (authResult, error) in
// ...
if #available(iOS 10.0, *) {
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
}
Messaging.messaging().delegate = self
UIApplication.shared.statusBarStyle = .default
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let viewController = mainStoryboard.instantiateViewController(withIdentifier: "gateway") as! gatewayViewController
window!.rootViewController = viewController
return true
}
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Firebase registration token: \(fcmToken)")
let dataDict:[String: String] = ["token": fcmToken]
NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
// TODO: If necessary send token to application server.
// Note: This callback is fired at each app startup and whenever a new token is generated.
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired till the user taps on the notification launching the application.
// TODO: Handle data of notification
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// Print message ID.
// if let messageID = userInfo[gcmMessageIDKey] {
// print("Message ID: \(messageID)")
// }
// Print full message.
print(userInfo)
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired till the user taps on the notification launching the application.
// TODO: Handle data of notification
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// Print message ID.
//if let messageID = userInfo[gcmMessageIDKey] {
// print("Message ID: \(messageID)")
//}//
// Print full message.
print(userInfo)
completionHandler(UIBackgroundFetchResult.newData)
}
But when trying to send a message on my console.firebase.com it gets labeled as "Completed" but my iPhone 6S don't shows the notification.
Notifications are also enabled in app capabilities
I need your help

I think you're not setting your APN token. Push your APNs token.
func application(_ application: UIApplication,didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let tokenParts = deviceToken.map { //data -> String in
return String(format: "%02.2hhx", $0)
}
Messaging.messaging().apnsToken = deviceToken
Messaging.messaging().setAPNSToken(deviceToken, type: .unknown)
UserDefaults.standard.synchronize()
}
