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.
