I am not able to receive data notification iOS swift 3

Question

I am following sampler project provided by firebase. Firebase Cloud Messaging sammple

My app delegate is

import UIKit
import Firebase
import FirebaseMessaging
import UserNotifications
import FirebaseInstanceID

//add firebase code app delegate code

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

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


func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.


    // Register for remote notifications. This shows a permission dialog on first run, to
    // show the dialog at a more appropriate time move this registration accordingly.
    // [START register_for_notifications]
    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 })

    } else {

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

        }

    application.registerForRemoteNotifications()

    // [END register_for_notifications]
    FirebaseApp.configure()

    completionHandler(UIBackgroundFetchResult.newData)
}
// [END receive_message]


func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    print("Unable to register for remote notifications: \(error.localizedDescription)")
}

// This function is added here only for debugging purposes, and can be removed if swizzling is enabled.
// If swizzling is disabled then this function must be implemented so that the APNs token can be paired to
// the InstanceID token.
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    print("APNs token retrieved: \(deviceToken)")

    // With swizzling disabled you must set the APNs token here.
    InstanceID.instanceID().setAPNSToken(deviceToken, type: InstanceIDAPNSTokenType.sandbox)

}


}

func application(received remoteMessage: MessagingRemoteMessage) {

    //get called when sending notification from POSTMAN and when app is open

    print("%@", remoteMessage.appData)

    print("%@", remoteMessage)

}


func resgisterNotificationToken(fcmToken:String){

    //let deviceId = UIDevice.current.identifierForVendor!.uuidString

    //let parameters = ["OTY": AppConstants.init().OS_TYPE,"REGID": fcmToken] as Dictionary<String, String>



}

}

I can receive notification which was sent from firebase console. i have upgraded my firebase library to latest 3.0 something.

also i am getting following warning. 'InstanceIDAPNSTokenType' is deprecated: Use FIRMessaging's APNSToken property instead.

kindly provide solution with code and give me server request structure so that i can test it from postman.

Thanks in advance.

Answer 1

Can you try setting the apn token like this:

FIRInstanceID.instanceID()
    .setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.unknown)

FIRInstanceID setAPNSToken

Set APNS token for the application. This APNS token will be used to register with Firebase Messaging using token or tokenWithAuthorizedEntity:scope:options:handler. If the token type is set to FIRInstanceIDAPNSTokenTypeUnknown InstanceID will read the provisioning profile to find out the token type.

Firebase API reference

It's working for me!

EDIT:

With Firebase version 4.0.0 the way to do it has changed:

Messaging.messaging()
    .setAPNSToken(deviceToken, type: MessagingAPNSTokenType.unknown)
