SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Diagnose data races, guides Swift concurrency migrations, and clarifies actor isolation and Sendable conformance for Swift 6 across codebases.

Core Features & Use Cases

  • Diagnose data races and concurrency issues in Swift projects
  • Provide migration guidance for Swift 6, async/await adoption, and actor isolation patterns
  • Offer best-practice references for concurrency tooling, linting, and safe patterns (MainActor, Sendable, and structured concurrency)
  • Support reusable patterns and step-by-step guidance for complex concurrency migrations across iOS/macOS codebases

Quick Start

Refactor a callback-based API to async/await and apply proper actor isolation practices.

FAQPage Schema
How do I migrate my Swift project to Swift 6 concurrency?▼

To migrate to Swift 6, you must analyze project settings and incrementally adopt async/await, implement actor isolation, and enforce Sendable conformance to eliminate data races.

What is the best way to refactor callback-based APIs to async/await in Swift?▼

The best way to refactor callback-based APIs to async/await is by applying proper actor isolation practices to safely manage state and structure asynchronous execution.

Why do I need Sendable conformance for Swift concurrency?▼

You need Sendable conformance for Swift concurrency to guarantee types are safe to pass across actor boundaries, effectively preventing data races during concurrent execution.

Can I use actor isolation to fix data races in my iOS codebase?▼

Yes, you can use actor isolation to fix data races in your iOS codebase by synchronizing access to mutable state and preventing concurrent modifications.

How does structured concurrency apply to Swift 6 migration?▼

Structured concurrency applies to Swift 6 migration by enforcing hierarchical task lifecycles, ensuring async/await operations are safely scoped and preventing unstructured task leaks.
