@jhampton, adding you as a reviewer here for context. This failure is legit; it is the failure I fixed in my other PR. Once that one gets merged, we will be able to update this pr and should see the test pass here.

Greptile Overview

Greptile Summary

Added new GitHub Actions workflow to test iOS example app builds on pull requests to main branch

• Sets up macOS runner with Xcode, Node.js 20, Ruby 3.2, and CocoaPods
• Installs dependencies for both root and example app
• Uses Expo prebuild to generate native iOS directory
• Builds iOS app to catch build failures in CI before merge
• Comment on line 15 says "Pin Xcode" but actually uses 'latest-stable' (not pinned)
• Missing explicit permissions block (other workflows use contents: read)
• Missing newline at end of file

Confidence Score: 4/5

• Safe to merge with minor style improvements recommended
• Workflow follows good patterns from existing CI workflows, properly sets up iOS build environment, and achieves stated goal of testing iOS builds. Only style issues: misleading comment about pinning Xcode, missing permissions block, and missing newline at EOF
• No files require special attention

Small suggestion on the comment for future improvement, otherwise LGTM once it runs successfully. https://github.com/youversion/platform-sdk-reactnative/actions/runs/21490549279 shows an error about missing "jobs", suggestion below.

@jhampton how about we go ahead and merge this and we can track somewhere the possible improvements.
