These errors occur when building from the command line or in Xcode itself:

Why are we using Xcode 14.3?

Devices which have been upgraded to iOS 16.4 can't be connected to Xcode with anything except the newest version of Xcode, which is 14.3. Unfortunately this is not yet officially released, it's only available currently as a release candidate, so it's entirely possible that the release candidate is somehow broken.

Steps to reproduce

• Download and install Xcode 14.3 RC 2
• Generate a clean React Native 0.71.4 project
  • npx react-native@latest init clean_rn_project
• Build the project for iOS
  • cd clean_rn_project
  • npx react-native run-ios
• The build error occurs during this first build.

This is reproduced in a clean RN project so no code is necessary.
