Firebase push notifications custom sound

Question

I am currently working on an app and I have implement firebase Push Notification service into my app. I am recieving notification on my iphone but I am unable to set the custom alert sound that I want.

• I added the sound as a .caf
• I added the sound to the Copy Bundle Resources

using print (userInfo) I have collected this data that is incomming from Firebase

aps: {
alert =     {
    body = MSG;
    title = Title;
};
sound = default;}, {...}, sound: alarm.caf

I understand where the problem is, I just dont understand how to fix it so that the app plays my custom notification sound.

Answer 1

It's been over 5 years, but if someone still looking for an answer, here is what I did.

1. Make sure you have configured Firebase Messaging & receiving Notifications.

2. Add .caf ( sound file ) to the app. It must be visible on 'Target' - > 'Build Phases' & then under 'Copy Bundle Resources'

3. Delete the app from the device ( This is important )

4. I use Postman as my server, so message format would be,

   { 
    "notification": {
    "title": "Hello",
    "sound":"small_message.caf",
    "body": "You have a new Job"
   },
   
   "to": "your device token"
   }
