Xcode – Build failed with error: Undefined symbol: ___darwin_check_fd_set_overflow

I’ve created a new React Native project with npx react-native init AwesomeProject.

When I try to run ios app with npx react-native run-ios, build fails with the following error.

Undefined symbol: ___darwin_check_fd_set_overflow

I am using XCode 11.3.

After some research, I found that upgrading XCode version could solve the problem. But I cannot upgrade XCode version for some reason.

Can anyone help to fix this?
