macOS Development

You MUST use this skill for ANY macOS-specific development including windows, menus, sandboxing, distribution, AppKit bridging, and macOS SwiftUI differences.

Quick Reference

Symptom / Task	Reference
Window management (WindowGroup, Window, MenuBarExtra)	See `skills/windows.md`
Menu bar, commands, keyboard shortcuts	See `skills/menus-and-commands.md`
Table, Inspector, NavigationSplitView, focus	See `skills/swiftui-differences.md`
App Sandbox, file access, security-scoped bookmarks	See `skills/sandbox-and-file-access.md`
Developer ID, notarization, Sparkle auto-updates	See `skills/direct-distribution.md`
NSViewRepresentable, NSHostingController, AppKit bridging	See `skills/appkit-interop.md`

Cross-Suite Routes

These topics overlap with macOS development but live in separate suites:

SwiftUI (shared iOS/macOS)

View state, data flow, @Observable → See axiom-swiftui
Navigation (NavigationStack basics) → See axiom-swiftui (skills/nav.md)
Layout (ViewThatFits, AnyLayout) → See axiom-swiftui (skills/layout.md)
Animations → See axiom-swiftui (skills/animation-ref.md)

Data & persistence

SwiftData, Core Data, GRDB → See axiom-data
CloudKit sync → See axiom-data

Concurrency

Swift 6 concurrency, actors, Sendable → See axiom-concurrency

Other

Accessibility (VoiceOver, Dynamic Type) → See axiom-accessibility
Networking (URLSession, Network.framework) → See axiom-networking
Security (Keychain, passkeys, encryption) → See axiom-security

Conflict Resolution

axiom-macos vs axiom-swiftui: When working on a macOS SwiftUI app:

Use axiom-macos for macOS-only concerns: windows, menus, commands, sandboxing, distribution, Table, Inspector, AppKit bridging
Use axiom-swiftui for cross-platform SwiftUI: navigation, layout, state management, animations
Both may apply: A macOS app using NavigationSplitView with Table needs axiom-macos for Table specifics and axiom-swiftui for NavigationSplitView basics

axiom-macos vs axiom-security: For sandbox and code signing:

Use axiom-macos for macOS App Sandbox, security-scoped bookmarks, file access entitlements, Developer ID signing
Use axiom-security for Keychain storage, encryption, passkeys, certificate management
