iOS React/RCTComponent.h cannot be found

Had problem installing the slider with React Native 0.37 on iOS.

Got errors after running react native link because RCTComponent.h and RCTViewManager.h imports in the volume slider files were not set to be React/* rather than /*. The React dir did not exist

Had to follow this solution here

Follow the link instruction of doc and add to your library project in Xcode the file React.xcodeproj located at node_modules/react-native/react and build again
