Pull Request Overview

This PR updates CI workflows to use Python 3.12 to resolve PEP 604 union syntax compatibility issues, and excludes Source/Data/** from Swift/C++ CI triggers since changes to dictionary data don't require rebuilding the Swift or C++ code.

• Updates Python version from implicit 3.9 to explicit 3.12 in Xcode and CodeQL workflows
• Adds paths-ignore filters to skip CI runs when only Source/Data/** changes
• Bumps GitHub Actions versions to latest (checkout@v5, setup-python@v6, commit-comment@v4)

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis 🔶 719 - Partially compliant Compliant requirements: Ensure CI uses Python 3.12 to align with modernization. Non-compliant requirements: Modernize the Python codebase to Python 3.12+. Adopt type hints and clean architecture across Python code. Requires further human verification: Verify all Python modules in the repository are updated to 3.12+ syntax and type hints. Validate runtime compatibility on developer environments beyond CI.

⚡ Recommended focus areas for review Workflow Paths The negative path '!Source/Data/**' is added; confirm it properly excludes only Swift/C++ code in that folder without suppressing desired CodeQL coverage or other language scanning. - '!Source/Data/**' pull_request: branches: [ "master" ] paths: - '**/*.swift' - '**/*.cpp' - '**/*.mm' - '**/*.m' - '**/*.h' - '*.xcodeproj/**' - '*.xcworkspace/**' - '.github/workflows/codeql.yml' - '!Source/Data/**' Python Setup Placement Python 3.12 is set up, but no explicit usage step is shown in this workflow; verify any Python-based tooling or scripts invoked by Xcode CI rely on this version and PATH resolution on macOS runners. - uses: actions/checkout@v5 - uses: actions/setup-python@v6 with: python-version: '3.12' Action Upgrade Upgrading commit-comment action to v4 may change permissions or defaults; ensure required permissions (contents: write) are granted and that 'body-path' still behaves as expected. uses: peter-evans/commit-comment@v4 with: body-path: 'codecov_comment.md'
