`React/RCTBridgeModule.h` file not found

Question

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

Answer 1

I've encountered this issue while upgrading from 0.58.4 to new react-native version 0.60.4. Nothing from what i found on the internet helped me, but I managed to get it working:

Go to build settings, search for 'Header search paths', select the entry, press DELETE button.

I had these values overriden, and looks like they fell back to defaults after deletion. Also Cocoapods was complaining about it with messages in Terminal after pod install:

[!] The `app [Release]` target overrides the `HEADER_SEARCH_PATHS` build setting defined in `Pods/Target Support Files/Pods-app/Pods-app.release.xcconfig'. This can lead to problems with the CocoaPods installation

Answer 2

I was able to build a debug, but I was unable to build an archive.

I solved this issue by dragging React.xcodeproj found in /node_modules/react-native/React to my root directory in Xcode, then added React as a target dependancy in build phases > target dependencies.

If you want to keep Parallelise Build enabled and avoid the missing header problems, then provide a pre-build step in your scheme to put the react headers into the derived-data area. Notice the build settings are coming from the React project in this case. Yes it's not a thing of beauty but it gets the job done and also shaves a lot of time off the builds. The prebuild step output ends up in prebuild.log. The exact headers you'll need to copy over will depend on your project react-native dependencies, but you'll get the jist from this.

Get the derived data directory from the environment variables and copy the required react headers over.

#build_prestep.sh (chmod a+x)
derived_root=$(echo $SHARED_DERIVED_FILE_DIR|sed 's/DerivedSources//1')
react_base_headers=$(echo $PROJECT_FILE_PATH|sed 's#React.xcodeproj#Base/#1')
react_view_headers=$(echo $PROJECT_FILE_PATH|sed 's#React.xcodeproj#Views/#1')
react_modules_head=$(echo $PROJECT_FILE_PATH|sed 's#React.xcodeproj#Modules/#1')
react_netw_headers=$(echo $PROJECT_FILE_PATH|sed 's#React/React.xcodeproj#Libraries/Network/#1')
react_image_header=$(echo $PROJECT_FILE_PATH|sed 's#React/React.xcodeproj#Libraries/Image/#1')

echo derived root = ${derived_root}
echo react headers = ${react_base_headers}

mkdir -p ${derived_root}include/React/

find  "${react_base_headers}" -type f -iname "*.h" -exec cp {} "${derived_root}include/React/" \;
find  "${react_view_headers}" -type f -iname "*.h" -exec cp {} "${derived_root}include/React/" \;
find  "${react_modules_head}" -type f -iname "*.h" -exec cp {} "${derived_root}include/React/" \;
find  "${react_netw_headers}" -type f -iname "*.h" -exec cp {} "${derived_root}include/React/" \;
find  "${react_image_header}" -type f -iname "*.h" -exec cp {} "${derived_root}include/React/" \;

The script does get invoked during a build-clean - which is not ideal. In my case there is one env variable which changes letting me exit the script early during a clean.

if [ "$RUN_CLANG_STATIC_ANALYZER" != "NO" ] ; then
    exit 0
