Axiom Swift

This is the skill to reach for when Claude's Swift suggestions smell outdated or when you're working with newer language features. It covers modern idioms that replace common hallucinations like Date() and DispatchQueue.main.async, plus deep dives on ownership conventions (borrowing, consuming, noncopyable types), the Transferable protocol for drag and drop, debug deep links for simulator testing, and tvOS-specific gotchas like the dual focus system and missing Documents directory. The conflict resolution section is honest about when to use axiom-concurrency or axiom-performance instead. If you've ever had Claude generate Swift code that compiles but feels five years old, or you're implementing ShareLink and hitting silent cross-app failures, this addresses both problems directly.

Swift Language & Platform

You MUST use this skill for ANY Swift idiom review, ownership/noncopyable types, Transferable/drag-and-drop, debug deep links, or tvOS development.

Auditors are skills here. Where this router says "Launch some-auditor agent", invoke the matching Codex skill instead — same procedure, no Claude Code agent required.

Available: axiom-swift-simplifier.

The ones that shell out — builds, tests, simulators, crash symbolication — need shell access to run.
