Integration of react-native-reanimated with Salesforce React Native app causing Pod install and Fabric architecture issues

[iamsurajnambiar]

I am integrating react-native-reanimated into my Salesforce React Native app. During pod install, I encountered the following error:

[!] An error occurred while processing the post-install hook of the Podfile.

no implicit conversion of nil into String

/Users/ind040101397/Documents/forcedotcom/sgnext/node_modules/react-native/scripts/cocoapods/utils.rb:83:in join' /Users/ind040101397/Documents/forcedotcom/sgnext/node_modules/react-native/scripts/cocoapods/utils.rb:83:in block (2 levels) in set_node_modules_user_settings'
...
/opt/homebrew/Cellar/cocoapods/1.15.2_1/libexec/bin/pod:25:in `

'

Following the resolution from a similar thread, I modified my post_install section as follows:

  post_install do |installer|
    if defined?($config[:reactNativePath]) && !$config[:reactNativePath].nil?
      react_native_post_install(
        installer,
        $config[:reactNativePath],
        :mac_catalyst_enabled => false
      )
    else
      puts "reactNativePath is not defined or is nil!"
    end
  end

After following this approach and cleaning the pod cache (pod cache clean --all), I managed to bypass the initial error. However, I encountered a Fabric architecture issue afterward when running npx react-native run-ios.

Steps Taken:
cd ios
pod cache clean --all
pod install
Removed .xcode.env.local
Tried running the project again: npx react-native run-ios

Current Issue:
I'm now stuck with a Fabric architecture issue, which seems related to the integration of react-native-reanimated with Salesforce's Mobile SDK. I've tried several methods, but nothing has resolved the problem.

Environment:

React Native: 0.74
react-native-reanimated version: 3.15.4
macOS: Apple Silicon M2 Pro
Cocoapods: 1.15.2
Any advice or further troubleshooting steps would be greatly appreciated!

We just released Mobile SDK 12.2, which depends on React Native 0.74.5.
Could you try and see if you are still having the same issues?
