[Davy Zhang]

i don't know how i can receive notification plz can people can you guide me.

so technically i receive the notification on the android Phone but no on my Ios Phone.

what i already : 

firebase with a KEY APNs ( it work)

get the googleService info

update the info plist : FirebaseAppDelegateProxyEnabled to NO

update the capabilities : background mode with the background fetch/ push notification and communication notification

here is my code : 

AppDelegate : 

import UIKit

import GooglePlaces

import Firebase

import FirebaseMessaging

import UserNotifications

@main

class AppDelegate: UIResponder, UIApplicationDelegate, MessagingDelegate, UNUserNotificationCenterDelegate {

    

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

        // Override point for customization after application launch.

        UserDefaults.standard.setValue(false, forKey: "_UIConstraintBasedLayoutLogUnsatisfiable")

        //google places key

        GMSPlacesClient.provideAPIKey("googleAPIKey")

        

        // Configure Firebase

        FirebaseApp.configure()

        Messaging.messaging().delegate = self

        // Request authorization to receive push notifications

        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { granted, error in

            guard granted else { return }

            // Register with FCM

            UNUserNotificationCenter.current().delegate = self

            DispatchQueue.main.async {

                application.registerForRemoteNotifications()

            }

        }

        return true

    }

    

    // Handle failing to register for push notifications

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

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

    }

    

    // Handle receiving an FCM registration token

    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String?) {

        print("FCM registration token: \(fcmToken ?? "000")")

        // Do something with the token

    }

    

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

        

  

        // Set APNS device token in FCM instance

        Messaging.messaging().setAPNSToken(deviceToken, type: .prod)

        

        // Retrieve FCM token

        Messaging.messaging().token { token, error in

            if let error = error {

                print("Error retrieving FCM token: \(error.localizedDescription)")

            } else if let token = token {

                print("FCM token: \(token)")

            }

        }

    }

}

on my view Controller how i sent the notification : 

 func envoyerNotifClient(token:String){

        // Créer une demande de notification

        let notification = [

            "to": token,

            "notification": [

                "title": "Batigreen",

                "body": "vous avez recu un message !"

            ]

            

        ] as [String : Any]

        // Convertir la demande de notification en JSON

        let jsonData = try? JSONSerialization.data(withJSONObject: notification)

        // Configurer la requête HTTP

        let url = URL(string: "https://fcm.googleapis.com/fcm/send")!

        var request = URLRequest(url: url)

        request.httpMethod = "POST"

        request.httpBody = jsonData

        request.addValue("application/json", forHTTPHeaderField: "Content-Type")

        request.addValue("key=myKey", forHTTPHeaderField: "Authorization")

        // Envoyer la notification

        let task = URLSession.shared.dataTask(with: request) { (data, response, error) in

            if let error = error {

                print("Erreur lors de l'envoi de la notification: \(error.localizedDescription)")

                return

            }

            if let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode != 200 {

                print("Erreur lors de l'envoi de la notification, code de réponse HTTP: \(httpResponse.statusCode)")

                return

            }

            print("Notification envoyée avec succès")

        }

        task.resume()

    }
