iOS build fails due to 11 target instead of 12

[norbertschuler]

We are currently using a patch in our Podfile named __apply_Xcode_12_5_M1_post_install_workaround which set the IPHONEOS_DEPLOYMENT_TARGET to 11 for all Pods using a lower target. Unfortunately for my latest Xcode Version 14.3 on M1 architecture the build fails with missing 'butter/map.h' file not found until I set the Pods target to 12 at minimum.

I changed the file node_modules/react-native/scripts/react_native_pods.rb containing the patch to this code (just exchanging 11 to 12) - I have not yet found a good way to persist this change for our repository:

...
def __apply_Xcode_12_5_M1_post_install_workaround(installer)
  # Flipper podspecs are still targeting an older iOS deployment target, and may cause an error like:
  #   "error: thread-local storage is not supported for the current target"
  # The most reliable known workaround is to bump iOS deployment target to match react-native (iOS 11 now).
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      # ensure IPHONEOS_DEPLOYMENT_TARGET is at least 12.0
      deployment_target = config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'].to_f
      should_upgrade = deployment_target < 12.0 && deployment_target != 0.0
      if should_upgrade
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
      end
    end
  end
