RN 0.42.0 iOS 'Lexical Preprocessor Issue'. React header files not found.

See original GitHub issue

Description

Fresh RN project initializations have been failing to build and run for me. I have been facing this issue for about a week and a half and tried several different things. I simply cannot get a React Native project to build on my machine. Header files cannot be found for whatever reason. Any help would be very appreciated.

Reproduction

react-native init testproject open Xcode project Clean project Build project Build fails

I tried the solution in here: https://twitter.com/skellock/status/818813810781908992, and the problem solved. Remember to disable parallelize build in scheme configuration and add React target before your own project target. Hope it helps.

For me - rm -rf node_modules watchman watch-del-all rm -fr $TMPDIR/react-*, restart xcode, rm -fr $TMPDIR/react-* helped.
