`React/RCTBridgeModule.h` file not found

Getting this error while building a react-native iOS app on xcode.

Started getting this error after npm install and rpm linking react-native-fs library. But after searching online for a solution, I noticed that many people are getting the same error while installing other react native libraries.

A possible solution suggested by many is, Adding the following under "Build Settings" -> "Header Search Paths".

$(SRCROOT)/../node_modules/react-native/React - (Recursive)

But no luck with this solution, still getting the same error

In my case this particular problem happened when I was trying to archive a 0.40+ react-native app for iOS (solution was found here: Reliable build on ^0.39.2 fails when upgrading to ^0.40.0).

What happened was that Xcode was trying to build the react-native libraries in parallel and was building libraries with implicit react dependencies before actually building the react library.

The solution in my case was to:

1. Disable the parallel builds:

   • Xcode menu -> Product -> Scheme -> Manage Shemes...
   • Double click on your application
   • Build tab -> uncheck Parallelize Build

2. Add react as a project dependecy

   • Xcode Project Navigator -> drag React.xcodeproj from Libraries to root tree
   • Build Phases Tab -> Target Dependencies -> + -> add React

Make sure you disable Parallelise Build and add React target above your target
