How to change sound of push notifications of an iOS app programmatically?

Question

I working on an iOS app for which I am required to change sound for push notifications. I am using Firebase Console to send notifications.

I put notification sound file in project and send its name in custom data through Firebase messaging in sound key. I found this solution after hours of searching but this solution doesn't seem to work. Is it even possible in iOS? If so how?

All you need to do are:

1. Make sure you've added the sound file to your project. Double check it in Project -> Build Phases. Supported types are aiff, wav, or caf as mentioned in this documentation UNNotificationSound.

2. The push notification payload must have a sound field that matches with the file name from the previous step. In this case is "sound": "pushSound.wav". I've created a mockup in Push Notification Console. The payload should be something like:

{
 "aps": {
 "alert": {
 "title": "Who's that?"
 "body": "Ringgggg....."
 }
 "sound": "pushSound.wav" //<- here
 }
}

It's supposed to work as usual if the project didn't include any Notification Extension.
