 ### Notes for Developers: If you experience a compiler error above!

 1. If you're using frameworks - Ensure your pods are installed with the `USE_FRAMEWORKS=1` environment variable:
    USE_FRAMEWORKS=1 bundle exec pod install

 2. Verify that your `Podfile` includes either:
        use_frameworks! :linkage => :dynamic
    or
        use_frameworks! :linkage => :static

 3. Refer to these GitHub issues for more details:
    - https://github.com/plaid/react-native-plaid-link-sdk/issues/713
    - https://github.com/plaid/react-native-plaid-link-sdk/issues/732
    - https://github.com/plaid/react-native-plaid-link-sdk/issues/747

 ### Troubleshooting:
 - If `USE_FRAMEWORKS` is not working, ensure it is correctly passed as a preprocessor macro in your Xcode build settings.
 - For new architecture projects, confirm `RCT_NEW_ARCH_ENABLED` is properly set in your environment.
