Use this skill when the user:
- Asks about macOS development best practices
- Wants code review for macOS/Swift projects
- Needs help with SwiftUI, SwiftData, or AppKit
- Is implementing macOS 26 (Tahoe) features
- Wants UI/UX review against HIG
- Needs architecture guidance for macOS apps

How to Use
- Identify user's need from their question
- Read relevant module files from subdirectories
- Apply the guidance to their specific context
- Reference Apple documentation when needed
Example Workflow
User asks about SwiftData performance:
- Read
swiftdata-architecture/performance.md
- Read
swiftdata-architecture/query-patterns.md if relevant
- Apply recommendations to their code
