REAIOSScheduler.h Not Found Error

[Raamzeez]

When trying to create a production build of my react-native project (bare workflow) with expo, the build fails when running Fastlane. Specifically, when Fastlane is compiling react-native-reanimated.

Upon further inspection of my node_modules folder, it appears that REAIOSScheduler.h does exist in the node_modules/react_native_reanimated/ios/native directory. Does anyone know why this error keeps occurring? I have done multiple things, including reverting code changes to a previous version of my application that used to work, deleting and reinstalling all libraries (including react-native-reanimated) numerous times, and clearing the cache.

"react-native-reanimated": "~2.3.1", <-- As reported in package.json

Hey, please don't use 2.3.1. The latest version is 2.10.0. Let us know if it works for you.

Thanks for the help! I guess there was some issue with expo where it was restricting react-native-reanimated from getting upgraded even though I kept uninstalling and reinstalling it, and I didn't notice that it was not the latest version. This appears to have solved my issue. I am getting other issues from my project but the error doesn't seem to be coming from react-native-reanimated, so I am confident that this solved the issue.

Quick Update: I was able to fix the other issues, which involved removing unused packages with yarn remove [package-name] in my project because there were linker issues happening with XCode.
