Firebase iOS push notification custom sound not playing? - firebase

Question

I'm using firebase push notification service in my iOS app which is developed using swift 3. Currently im getting notification. But i have configured custom sound for notification alert. What happen is when app is closed im getting a default sound not the cutmized sound. But i want to play the custom sound. How can i do this ?
Here is what i have done:
import UIKit
import UserNotifications
import Firebase
import FirebaseInstanceID
import FirebaseMessaging
import GoogleMaps
import GooglePlaces
import GooglePlacePicker
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
//For FireBase Configs
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
FirebaseApp.configure()
//FireBase Configs
return true
}
func application(_ application: UIApplication,open url: URL,sourceApplication: String?, annotation: Any) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application,open: url as URL!,sourceApplication: sourceApplication,annotation: annotation)
}
//FireBase Notifications Begins
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
//play alert sound
utilityHelper.playAudio(fileName: "udio", fileExtenstion: "mp3")
let json = JSON(userInfo)
NSLog("Received a Notificat`ion: \(json)")
completionHandler(UIBackgroundFetchResult.newData)
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
NSLog("show notification")
completionHandler(UNNotificationPresentationOptions.alert)
}
func application(received remoteMessage: MessagingRemoteMessage) {
}
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
NSLog("Refreshed Firebase registration token: \(fcmToken)")
}
func application(_ application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken as Data
NSLog("Register FireBase Token.")
}
//FireBase Notifications End
}
How can i do this, any help would appreciate?

What I recently discovered is that on target under ios9 custom sound doesnt play as well as on device with ios 10.0.*.
So just set your build target either >= 9 or use device with iOS >= 10.1
