I\'m testing React Native 0.56.0-rc.2 on Mac OS Mojave and Xcode 10.
Running:
react-native init TestProject --version=\"0.56.0-rc.2\" cd TestProject npm
Running this from the project directory fixed it for me:
cd ./node_modules/react-native/third-party/glog-0.3.4 && ../../scripts/ios-configure-glog.sh
This manually triggers the config script
