Answer 1

I had the same issue and got it resolved by removing references to $(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME) from our project.pbxproj file as mentioned in this comment: https://github.com/facebook/react-native/issues/31179#issuecomment-829536845. I would also run all the clean up commands suggested there.

Answer 2

Deleting the text from project.pbxproj file is always too risky. We have an alternative solution
