Bounty: 50

I am able to run the app in Debug mode in XCODE and simulator without any errors. But when I build for Release Mode the build fails with below 2 errors:

  1. ‘FirebaseCore/FirebaseCore.h’ file not found
  2. Could not build Objective-C module ‘Firebase’

I have been trying different solutions available on Stackoverflow and gitHub over last 10 days but know seems to be working, below are the details.
