Apple Documentation Router

Apple bundles for-LLM markdown documentation inside Xcode. These are authoritative, up-to-date guides and diagnostics written by Apple engineers. Read them directly as files (in Claude Code, with the Read tool), no MCP server or special tool required.

When to Use

• You need the exact API signature or behavior from Apple
• An Axiom skill references an Apple framework and you want the official source
• A Swift compiler diagnostic needs explanation
• The user asks about a specific Apple framework feature

Priority: Axiom skills provide opinionated guidance (decision trees, anti-patterns, pressure scenarios). Apple docs provide authoritative API details. Use both together.

How to Read These Docs

Axiom's session context names the Xcode the user has switched to. In Claude Code it lists the literal base directories ("Apple for-LLM Documentation: Xcode detected at <path>"); other harnesses name the app ("Installed on this machine: Xcode … (<path>)"), substitute that .app for /Applications/Xcode.app in the table below. Read <base>/<filename> as a file (the Read tool in Claude Code).

Default Xcode location (/Applications/Xcode.app) base directories:

Content	Base directory
AdditionalDocumentation guides	/Applications/Xcode.app/Contents/PlugIns/IDEIntelligenceChat.framework/Versions/A/Resources/AdditionalDocumentation/
Swift compiler diagnostics	/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/share/doc/swift/diagnostics/

Example invocation Claude should produce:

Read /Applications/Xcode.app/Contents/PlugIns/IDEIntelligenceChat.framework/Versions/A/Resources/AdditionalDocumentation/SwiftUI-Implementing-Liquid-Glass-Design.md
