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?

Try followings:

  • comment all flipper function in podfile
  • remove flipperInit in appDelegate
  • remove openSSl in podfile.lock
  • pod install,
  • clean project
  • run again

I could solve with this.

I could solve this issue by downgrading React Native version to 0.61.5.
