FAQPage Schema
How do I migrate an existing Swift project to Swift 6 strict concurrency?

Swift 6 migration involves enabling strict concurrency settings, addressing data races, and adopting actor isolation. This Skill provides actionable migration steps, best practices, and concrete patterns to safely transition your existing codebase to structured concurrency.

What is actor isolation and how does it prevent data races in Swift?

Actor isolation protects mutable state by serializing access, preventing data races in Swift Concurrency. This Skill provides concrete patterns for using actors and Sendable types to ensure safe, efficient concurrent code without reentrancy pitfalls.

Can I use async/await patterns in both apps and libraries?

Yes, async/await patterns apply to both apps and libraries, requiring strict Sendable conformance and actor isolation. This Skill provides a pattern library with concrete examples for tasks, actors, and Sendable types to ensure safe concurrency across different Swift project types.

What's the best way to debug Swift concurrency issues and reentrancy risks?

Debugging Swift concurrency issues requires understanding structured concurrency and identifying unsafe data access patterns. This Skill guides you through best practices and concrete patterns to minimize reentrancy risks and resolve data races effectively.

When do I need to use Sendable types in Swift Concurrency?

Sendable types are needed when passing data across concurrent boundaries to compile under Swift 6 strict concurrency. This Skill provides concrete patterns and best practices for conforming types to Sendable, ensuring safe data access across actors and tasks.
