Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?

[szydlovsky]

Hey @AuroPick! Before we go down the podifle and try finding any issues there - make sure to install pods the way react native now suggests:
cd ios && bundle install && bundle exec pod install
Let me know if anything changes.
You could also clean caches before the operation - git clean -xdf in the project root (you will also need to reinstall packages after the clean)

Hi @szydlovsky

I tried but didn't work.

$config[:reactNativePath] becomes nil outside the shared def after upgrade to 3.6.0

I invoked use_native_modules! again in the post_install. It looks like it is working.

post_install do |installer|
  config = use_native_modules!

  # https://github.com/facebook/react-native/blob/main/packages/react-native/scripts/react_native_pods.rb#L197-L202
  Pod::UI.puts "reactNativePath #{config[:reactNativePath]}"
  react_native_post_install(
    installer,
    config[:reactNativePath],
    :mac_catalyst_enabled => false
  )
  __apply_Xcode_12_5_M1_post_install_workaround(installer)
end

[szydlovsky]

@AuroPick If you say it works then I can safely close the issue, especially that the logs of the pod install don't point to anything associated with Reanimated
