About macos-development
macos-development is a skill for developers building or reviewing macOS apps with Swift. It organizes guidance into modules covering coding practices, architecture, SwiftData, platform capabilities, and UI review.
Key features
- 01Swift 6+ language and concurrency guidance
- 02SwiftData schema, query, and performance advice
- 03Architecture and modular design patterns
- 04macOS 26 API and platform integration topics
- 05SwiftUI and AppKit interoperability guidance
- 06HIG, accessibility, and UI review guidance
Use cases
- 01Review Swift code in a macOS project
- 02Plan an app architecture or audit an existing app
- 03Investigate SwiftData performance and queries
- 04Assess a macOS interface against HIG and accessibility

From the project READMEmacOS Development Expert
Comprehensive guidance for macOS app development. This skill aggregates specialized modules for different aspects of macOS development.
When This Skill Activates
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.mdif relevant - Apply recommendations to their code
