How does this skill prevent data races?

It implements Actor-based isolation and utilizes the Sendable protocol to ensure that mutable state is only accessed in a thread-safe manner.

Does it support parallel task execution?

Yes, it covers structured concurrency tools like 'async let' and 'TaskGroups' for managing multiple concurrent operations efficiently.

What version of Swift does this concurrency skill support?

This skill focuses on the modern concurrency model introduced in Swift 5.5 and refined in subsequent versions.

Can this skill help with UI-specific threading?

Yes, it provides implementation patterns for @MainActor to ensure UI updates always occur safely on the main thread.

Can it help me refactor legacy Grand Central Dispatch (GCD) code?

Absolutely, it provides patterns and best practices for bridging legacy completion handlers and dispatch queues into modern async/await code.

Mobile Development

Implements safe, performant asynchronous code using Swift's modern concurrency model, including async/await, actors, and structured concurrency.

This skill provides specialized guidance for implementing Swift's modern concurrency framework, introduced in Swift 5.5. It enables the creation of thread-safe, efficient, and readable asynchronous code by leveraging async/await syntax, actor-based data isolation, and structured concurrency patterns like task groups. By focusing on these modern primitives, the skill helps developers eliminate common concurrency bugs such as data races, deadlocks, and 'callback hell,' ensuring that asynchronous operations are managed predictably and safely according to current Swift best practices.
