AvdLee/Swift-Concurrency-Agent-Skill

Add expert Swift Concurrency guidance to your AI coding tool (Agent Skills open format): safe concurrency, performance optimization, and Swift 6 migration.

What it solves

This project provides expert-level guidance for AI coding tools to help developers implement safe concurrency, optimize performance, and migrate existing codebases to Swift 6. It addresses common challenges such as data races, isolation errors, and the complexities of transitioning from closure-based code or Combine/RxSwift to modern Swift Concurrency.

How it works

It is packaged as a portable Agent Plugin (spec 1.0.0) following the Agent Skills open format. This allows AI agents (such as Claude Code, Cursor, and ChatGPT) to automatically discover and use a structured set of reference files and decision trees located in the skills/ directory. The agent uses these references to provide accurate, industry-standard advice on actors, tasks, Sendable conformance, and memory management.

Who it’s for

  • Developers and teams migrating to Swift 6 or strict concurrency.
  • Engineers debugging data races or flaky asynchronous tests.
  • Swift developers seeking performance-minded concurrency patterns using actors, tasks, and async streams.

Highlights

  • Swift 6.2 Ready: Includes support for the latest features like default actor isolation and isolated deinit.
  • Broad Tool Compatibility: Compatible with Claude Code, Cursor, ChatGPT, Codex, and other tools supporting the Agent Plugins spec.
  • Comprehensive Reference Library: Includes dedicated guides on Core Data integration, memory management, and async algorithms.
  • Non-Opinionated: Focuses on compile-time safety and industry-standard best practices rather than specific architectural preferences.
