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
What you can do to get it right is:
1) npm uninstall reat-native-fs
to uninstall library
2)npm unlink react-native-fs
to unlink the library
Now the library is successfully removed and now install the lib again in your project and this time link everything manually. Sometime automatic linking causes this error.
