Firebase.h file not found with CocoaPods

I had the same issues on my project,

I wrote manually link the project and its libraries to solve the problem I followed this link steps it worked https://github.com/invertase/react-native-firebase-docs/blob/master/docs/installation/ios.md

Also, you must check you link binary with libraries on your Xcode project.

Another solution you can delete all pod depend on libs then you pod init add manual pod libs after pod install
