Apple Platform Build Tools Claude Code Plugin

Apple Platform Build Tools Claude Code Plugin

*Build, test, and archive Swift packages and Xcode projects for Apple platforms with Claude Code.*

About

Apple Platform Build Tools Claude Code Plugin is a Claude Code plugin with an Agent Skill and a Subagent for building Apple platform products.

- Agent Skill: Reference documentation for the xcrun developer tool ecosystem — xcodebuild, swift build, simctl, devicectl, code signing, profiling, distribution, and binary tools.
- Subagent: Discovers schemes, manages simulators and devices, runs builds, and returns results. Uses the Agent Skill.

Usage

Delegate build and test commands to the Subagent from your main programming agent. It reports results without exposing build logs, keeping the main agent's context window clean.

Use the Agent Skill directly when you need to understand xcodebuild, swift, simctl, devicectl, or other xcrun tool options, debug build failures, or construct commands with more control than the Subagent gives you.

Automatic

Both the Agent Skill and Subagent are exposed to Claude Code with descriptions of when to use them. Claude should read the Agent Skill when composing a complex xcodebuild command, or invoke the Subagent when a build needs to run. This is nondeterministic in practice and may change across Claude models and Claude Code versions.

Manual

To explicitly invoke the Agent Skill or Subagent, use natural language in Claude Code.

e.g.
use the builder agent to build the app
check with the builder agent that the tests pass
use the build skill to help me write an xcodebuild command for CI
