iOS Push Notifications doesn't work with Firebase

Question

I use Firebase to send Notification with my iOS app, I have followed all step in documentation :

Apple Developer Account Configuration
Generating a CSR file
Uploading CSF file
Preparing the APNs Certificate
Configuring Firebase for Push Notifications
Building the Firebase Notification in my app

When I try to send a Notification there isn't no problem found in Firebase, for one particular user or for all iOS device. But none of my device (real device obviously) receive notification.

I use the good Bundle, I enable notification in my application and there is the code in my AppDelegate :

import UIKit
import UserNotifications
import Firebase
import FirebaseInstanceID
import FirebaseMessaging

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate {

var window: UIWindow?

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


    UINavigationBar.appearance().barTintColor = Design.blue_es
    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName:UIColor.white]
    UINavigationBar.appearance().tintColor = UIColor.white


    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 })
        // For iOS 10 data message (sent via FCM
        Messaging.messaging().remoteMessageDelegate = self
    } else {
        let settings: UIUserNotificationSettings =
            UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }

    application.registerForRemoteNotifications()

    FirebaseApp.configure()

    return true
}
func application(received remoteMessage: MessagingRemoteMessage) {
    print(remoteMessage.appData)
}

// Called when APNs failed to register the device for push notifications
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    // Print the error to console (you should alert the user that registration failed)
    print("APNs registration failed: \(error)")
}

func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
    print("Firebase registration token: \(fcmToken)")
}
}

Have you uploaded P12 certificate of Push Notification certificate without key on firebase console ? — Krunal Darji
I uploaded P12 certificate, but I don't understand what you mean by "without key" — Thomas.O
when you export certificate from Keychain you can see one drop down arrow left to your Apple Push name expand it you will see Key icon — Krunal Darji
Ok, I have uploaded my P12 certificate with keychain for production and development notification, but I use the same CSR to generate them — Thomas.O

IN Swift 3

Configuring Your Apple Developer Account
Generating a CSR file
Uploading Your CSR File
Preparing the APNs Certificate
Configuring Firebase for Push Notifications
Building the Firebase Notification App
Installing the Firebase SDK Using CocoaPods
Adding GoogleService-Info.plist
Enabling Push Notifications
Initializing Push Notifications

AppDelegate of your Project

import UIKit
import SVProgressHUD
import UserNotifications
import Firebase
import FirebaseInstanceID
import FirebaseMessaging

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,UNUserNotificationCenterDelegate, MessagingDelegate {

    var window: UIWindow?


    static var appDelegate:AppDelegate!

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



        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 })
            // For iOS 10 data message (sent via FCM
            Messaging.messaging().remoteMessageDelegate = self
        } else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }

        application.registerForRemoteNotifications()

        FirebaseApp.configure()

        return true

    }

    func application(received remoteMessage: MessagingRemoteMessage) {
        print(remoteMessage.appData)
    }

    func application(application: UIApplication,
                     didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
        Messaging.messaging().apnsToken = deviceToken as Data
    }

}
