🌟 Summary

CI workflow now runs on macOS with Python 3.13 and enables Swift formatting, improving stability and ensuring Swift code is auto-formatted. 🛠️🍎

📊 Key Changes

• Switch workflow runner from ubuntu-latest to macos-26. 🖥️
• Add explicit Python setup using actions/setup-python@v6 with python-version: "3.13". 🐍
• Enable Swift formatting in Ultralytics Actions (swift: true). 🧹
• Keep existing formatters/checks (Ruff, docformatter, Prettier, codespell, AI labels, PR summaries) as-is. ✅

🎯 Purpose & Impact

• Resolve docformatter issues seen with Python 3.14 on macOS by pinning to 3.13, improving CI reliability. 🔧
• Enable automated Swift code formatting for the iOS app, ensuring consistent style across the codebase. 🎨
• Align CI environment with iOS tooling requirements (macOS), unlocking Swift-specific checks. 🔓
• Possible trade-offs: slightly longer CI times and use of macOS runner minutes, but fewer formatting-related failures and more consistent code quality. ⏱️✔️
