File contents

Lists the XcodeBuildMCP tools for macOS builds (build_macos, build_run_macos, test_macos, launch_mac_app, stop_mac_app) and references for app structure (MenuBarExtra, Settings, Windows), build tooling, AppKit bridging, and code-signing/notarization.

Best practices: support keyboard shortcuts for power users, use MenuBarExtra for utility apps, use WindowGroup/Window for multi-window apps and Settings for the preferences scene, notarize before distributing outside the App Store, and enable sandboxing for App Store submissions.

macOS Platform

macOS-specific development with window management and distribution tools.

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

explore-codebase - Analyze existing macOS patterns
research-expert - Verify latest macOS 26 docs via Context7/Exa
mcp__XcodeBuildMCP__build_macos - Build for macOS validation

After implementation, run sniper for validation.

Overview

When to Use

Building Mac desktop applications
