Is the Migrating To Swift Concurrency skill free?

Yes. The skill itself is free from kylehughes/the-unofficial-swift-concurrency-migration-skill. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Migrating To Swift Concurrency SkillProof Score?

8.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 5/5.

How do I install Migrating To Swift Concurrency?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Migrating To Swift Concurrency with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 8.8/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 9a959f8

It's literally Apple's public migration guide re-packaged with an index — solid and honest, but because that guide is already deep in Sonnet's training data, a baseline answer to a real Sendable-crossing-actor-boundary bug came out nearly identical to the skill-guided one; the skill's edge is citing exact compiler wording and the Boundaries.swift reference pattern rather than teaching anything new.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Migrating To Swift Concurrency does

Bundles Apple's full Swift Concurrency Migration Guide (Data Race Safety, Migration Strategy, Common Compiler Errors, Incremental Adoption, plus runnable Swift examples) as a loadable skill. Triggers when a user is moving a codebase to Swift 6 language mode, chasing Sendable/actor-isolation compiler errors, or asking how async/await interacts with existing GCD-based code.
