I want to send FCMToken into URL in IOS - ios

Question

I develop the app into webview. and configured firebase push notification successfully. messages are delivering fine.
But Now I want Device token into URL. by which I can send msg according to the token.
I write this code in Appdelegate.swift
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let token = deviceToken.map {String (format: "%02.2hhx", $0)}.joined()
print("Token : \(token)")
let preferences = UserDefaults.standard
preferences.setValue(token, forKey: "token")
preferences.synchronize()
}
//Changes
func application(_ application: UIApplication,
didFailToRegisterForRemoteNotificationsWithError
error: Error) {
// Try again later.
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: #escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
// Print message ID.
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
// Print full message.
print(userInfo)
completionHandler()
}
extension AppDelegate: MessagingDelegate {
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Firebase registration token: \(fcmToken)")
//Saving fcmToken to pass to the url
//Bhaskar Changes
let preferences = UserDefaults.standard
preferences.setValue(fcmToken, forKey: "token")
preferences.synchronize()
let token = Messaging.messaging().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 messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
print("Message Data", remoteMessage.appData)
}
and this code in Viewcontroller.swift
override func viewDidLoad() {
super.viewDidLoad()
//Retrieving the fcmToken
let prefs = UserDefaults.standard
let token = prefs.string(forKey: "token")
//?token= \(token as Optional)&device=ios
print("Token accessed : \(String(describing: token))")
webView.load(URLRequest(url: URL(string: "https://instaglamexpress.com/app/customer/?device=ios&token=\(String(describing: token))")!))
}
But everytime when I run the program. token is not storing into the token variable. it is showing "nil".
Am I following the right procedure.??
Please help me with the actual solution.

Maybe you forget to add Messaging.messaging().delegate = self in this way func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) will never be called.
