I have an iPhone app with chat module in [url removed, login to view] is written in Swift 3.0. App's backend is AWS and Chat is based on firebase. I need you to do the following:
1. Add sent,delivered,read ticks in chat same like whatsapp.
2. Add push notifications so that once the app is not open, user gets notification about new messages. You can use any srevice like onesignal etc.
I need it to be done before Tuesday evening i.e (Aug 1, 2017).
