Axiom Apple Docs Research

Routes Claude to Apple's bundled for-LLM documentation inside Xcode instead of guessing or hallucinating API details. When you're debugging a Swift 6.2 concurrency error, implementing Liquid Glass UI, or need the actual signature for a Foundation Models call, this tells Claude to read the markdown files Apple ships in Xcode.app directly with the Read tool. Covers 20 framework guides (SwiftUI, SwiftData, StoreKit, on-device LLM) and 46 compiler diagnostic explainers. Works best alongside other Axiom skills since those give you opinionated patterns and this gives you the ground truth from Apple engineers. Respects AXIOM_XCODE_PATH for beta installs.
