I am an iPhone app coder, and I\'m using Firebase as my backend server. Firebase doesn\'t support Push Notifications, so I\'ve been trying to figure out how to include them
If you want device to device push messages and not just server to device, the only solution I found was OneSignal. I was able to add basic device to device push message support for my app in about an hour and it is currently free.
Both Batch and Firebase only support server to device push messages, not what you want for a chat app
