[SOLVED] Why am I getting 'No such module' and 'fatal error: module' errors when trying to build a React Native app on iOS simulator with Xcode 14.3?

Why am I getting 'No such module' and 'fatal error: module' errors when trying to build a React Native app on iOS simulator with Xcode 14.3?

I've been trying to build a react-native (0.68.5) app via the ios simulator, which used to run ok when using Xcode 14.2, but now that I upgraded my Xcode version to 14.3 the app just won't compile. The errors I'm getting are:

fatal error: module 'React' in AST file .../React-Core.modulemap
No such module 'ExpoModulesCore'

I've created other projects from scratch and they work just fine, so I guess this is related to this project configuration.

I partially got the app to compile through Xcode by setting the Precompiled Bridging Header to No and using a Simulator with x86_64 architecture, but it doesn't connect to react-native cli, and when running react-native run-ios I keep getting the No such module 'ExpoModulesCore' error.

The steps I do to try to build the app are:

yarn install
cd ios && pod install
yarn ios (react-native run-ios)

I've tried to delete node_modules folder and yarn clean cache followed by a yarn install and it doesn't work.

I've also tried to do a arch -x86_64 yarn ios didn't work.

I've tried adding to my Podfile this line config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64" and didn't work.

And now in Xcode 14.3 the option to open using Rosetta was deleted.

Update: Fixed this by uninstalling everything related to xcode and re installing Xcode 14.2, enabled open with rosetta option and re-do the steps mentioned on my original question.
