Axiom Apple Docs

Points Claude at the markdown documentation Apple ships inside Xcode, the same files that power Xcode's own AI features. When you hit a Swift 6 concurrency error or need to know how Liquid Glass actually works, this reads the authoritative source directly using Claude's native Read tool. Covers 20 framework guides (SwiftUI, Foundation Models, SwiftData, StoreKit) and 46 compiler diagnostic explanations. No MCP server needed. The session hook detects your Xcode path automatically, so you just ask about the API and Claude pulls the real docs. Use it alongside other Axiom skills when you want Apple's word on something, not a hallucination.

Files

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).
