swift 3, ios 10 - push notification firebase is not received

Question

I am using this tutorial and this project as my references. This is my code in AppDelegate

import UIKit 
import UserNotifications 
import Firebase 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

     var window: UIWindow? 
     let gcmMessageIDKey = "gcm.message_id" 
     let preferences = UserDefaults.standard 

     func application(_ application: UIApplication, 
                 didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 

         Messaging.messaging().delegate = self 

         if #available(iOS 10.0, *) { 
             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() 
         FirebaseApp.configure() 
         return true 
     } 

     func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) { 
         if let messageID = userInfo[gcmMessageIDKey] { 
             print("Message ID: \(messageID)") 
         } 

         print("message1:",userInfo) 

     } 

     func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], 
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) { 
         if let messageID = userInfo[gcmMessageIDKey] { 
             print("Message ID: \(messageID)") 
         } 

         print("message2:", userInfo) 

         completionHandler(UIBackgroundFetchResult.newData) 

     } 

     func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {

         print("Unable to register for remote notifications: \(error.localizedDescription)") 
     } 

     func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { 

         print("APNs token retrieved: \(deviceToken)") 
         let apn = deviceToken.map { String(format: "%02.2hhx", $0) }.joined() 

     } 

     func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) { 

         Messaging.messaging().appDidReceiveMessage(userInfo) 

     } 
} 

@available(iOS 10, *) 
extension AppDelegate : UNUserNotificationCenterDelegate {

     func userNotificationCenter(_ center: UNUserNotificationCenter, 
                            willPresent notification: UNNotification, 
                            withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { 
         let userInfo = notification.request.content.userInfo 

         if let messageID = userInfo[gcmMessageIDKey] { 
             print("Message ID: \(messageID)") 
         } 

         print("userinfo", userInfo) 

         completionHandler([]) 
     } 

     func userNotificationCenter(_ center: UNUserNotificationCenter, 
                            didReceive response: UNNotificationResponse, 
                            withCompletionHandler completionHandler: @escaping () -> Void) { 
         let userInfo = response.notification.request.content.userInfo 

         if let messageID = userInfo[gcmMessageIDKey] { 
             print("Message ID: \(messageID)") 
         } 

         print("userinfo", userInfo) 

         completionHandler() 
     } 
 } 


extension AppDelegate : MessagingDelegate { 

     func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) { 

         print("Firebase registration token: \(fcmToken)") 

     } 

     func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) { 
         print("Received data message: \(remoteMessage.appData)") 

     } 
 } 

I got fcmtoken and APNs token. I've uploaded my Development APNs certificate. I've turned Push Notification on Capabilities to ON. I've tried it on my device. I've added GoogleService-Info.plist on my project. But I haven't received any notification from either the foreground or the background.

Did I make any mistake on my code? Or should I need to update my certificate? I am pretty new to this by the way.

Can anyone help me to solve it? I really appreciate it.

Thanks!

Answer 1

It's because I haven't uploaded the Production APNs Certificate, guys. I thought I don't need it because I saw on this tutorial and it used just Development APNs certificate.

Answer 2

You have to register your deviceTokenString or deviceTokenId in the database, and you have to have correct distribution or development certificate according to your need, this things are the basic need for to receive push-notification.

From your code, you didn't register deviceTokenString/Id.
