When upgrading to 0.64-rc3, error: Cycle in dependencies between targets 'FBReactNativeSpec'

Description

When upgrading to 0.64-rc3, I was stuck for many hours today on this compliation error:

Cycle in dependencies between targets 'BVLinearGradient' and 'FBReactNativeSpec'.

The initial target is irrelevant; if I removed BVLinearGradient it would still happen for many different native libraries and FBReactNativeSpec.

React Native version:

0.64-rc3 on iOS

Steps To Reproduce

Repro was consistent in my project. Maybe has something to do with the fact that I use use_frameworks!, and in the latest sample Podfile React Native does not include this directive.

Workaround

I was able to workaround this issue (and thus want to document it here for others who may get stuck) by:

Navigating to the FBReactNativeSpec target in the Pods project and deleting [CP-User] Generate Specs step.

I then navigated in the terminal to:

<project>/node_modules/react-native/scripts

And I manually ran from the terminal:

./generate-specs.sh

Here is a proposed solution from @gmapnl in the react-native-screens project:

https://github.com/software-mansion/react-native-screens/issues/842#issuecomment-812543933

post_install do |installer|
  react_native_post_install(installer)
  
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
    end
    
    if (target.name&.eql?('FBReactNativeSpec'))
      target.build_phases.each do |build_phase|
        if (build_phase.respond_to?(:name) && build_phase.name.eql?('[CP-User] Generate Specs'))
          target.build_phases.move(build_phase, 0)
        end
      end
    end
  end
end

This is not resolved. Still happens on 0.64.x
