SwiftUI Agent Skill - Write better code with Claude, Codex, and other AI tools

Paul Hudson has released an open-source SwiftUI agent skill that helps AI coding tools like Claude Code, Codex, and Gemini write better SwiftUI code. Installable via a single npx command, the skill covers common anti-patterns including deprecated API usage, accessibility issues (e.g., invisible VoiceOver buttons), performance pitfalls, and modern Swift idioms. It builds on Hudson's prior AGENTS.md work and includes checks for concurrency, design, and project hygiene, making AI-generated SwiftUI code more idiomatic and correct.
