Device Token not received when registering for remote notifications in Swift

Question

I somehow can not receive the device token when registering for remote notifications. I get the modal saying \"Do you want to allow App X to be able to send you notificaitons\",

Answer 1

For swift 4.0 please follow some steps :

1).On push notification in capabilities(TARGET)

2).Use this code in didFinishLaunchingWithOptions

  let settings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)

        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()

3).Add this also

 func application(_ application: UIApplication,
                 didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let tokenParts = deviceToken.map { data -> String in
        return String(format: "%02.2hhx", data)
    }

    let token = tokenParts.joined()
    print("Device Token: \(token)")  
}
