Summary of Changes

Hello @ncooke3, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a crucial validation step to the add_framework_script.rb script, ensuring that any specified Xcode project target actually exists before proceeding with modifications. This enhancement prevents potential issues arising from attempting to add frameworks or bundles to non-existent targets, providing clearer error feedback to the user. Furthermore, the internal logic for applying changes has been refactored to be more direct and efficient, leveraging the pre-validated target object.

Highlights

• Target Validation: The script now explicitly checks if the provided target name exists within the Xcode project. If the target is not found, the script will terminate with an error message, preventing silent failures.
• Code Simplification: The logic for adding frameworks, bundles, and files has been streamlined by removing redundant iterations over all project targets. The script now directly operates on the validated target object, improving efficiency and readability.

Code Review

The pull request addresses a critical issue in the add_framework_script.rb script where the script would fail silently if the specified target does not exist. The changes introduce a check for the target's existence and exit with an error message if the target is not found. Additionally, the code has been refactored to directly use the found target instead of iterating through all targets, improving efficiency and readability.

I like this but not the approach. Will punt for now.
