I had a old React-Native project which I wanted to give it a try again and when trying to run the project on iOS (Android works perfect) I get the error that Debug-iphonesimulator/GeneratedInfoPlistDotEnv.h file not found. If I run the project from the command react-native run-ios, than the build will succeed.

What can cause this issue and how can it be fixed?

I have tried to fix it with the comments from this issue but no success.

React-Native verision: 0.47

Full error:

<built-in>:1:10: fatal error: '/Users/myUser/Library/Developer/Xcode/DerivedData/Project-gcaxrvbcwgkfhkadevoqxcprxszw/Build/Products/Debug-iphonesimulator/GeneratedInfoPlistDotEnv.h' file not found

I fixed by copying file GeneratedInfoPlistDotEnv.h (in /ios/build/Build/Products/) to the path mentioned in the error message. The path mentioned in error message for simulator is not same as real phone, you need to copy for a second time.

The development for React Native just like droped in a deep black hole, what you need to do is just climb and climb and climb...

After run in Xcode once, path for GeneratedInfoPlistDotEnv.h is ''$(rn project path)/ios/build/Build/Products/"
Looks like something is different, but still i receive other errors now.

Changing the Info.plist preprocessor prefix file to works for me ${CONFIGURATION_BUILD_DIR}/../GeneratedInfoPlistDotEnv.h

kind of annoyingly ambiguous that this worked. Thank you though!

If you're coming from React version 0.60 and above, you should be referencing the package from GitHub instead of NPM. The author hasn't released auto-linking support on NPM yet, even though it's already merged!?

Try these steps after you unlink and uninstall the existing version of react-native-config. Remember to revert to default Info.plist preprocessor settings in XCode build settings.

  1. yarn add https://github.com/luggit/react-native-config.git

  2. cd ios && pod install

You don't have to add any other post-install scripts, just run the app like usual and it should work fine. Make sure you undo any other fixes before doing this.

@iRohitBhatia Have you tried clearing your node modules, cache and derived data folders and doing a fresh install?
Tried deleting the build folder, clean cache and node_modules. None of them worked for me
