Can it help migrate older Swift code?

Yes, the skill includes guidance for refactoring completion handlers and delegate patterns into modern async/await syntax.

How does this skill help with data races?

It provides patterns for using Actors, which isolate mutable state and ensure only one task can access it at a time, eliminating common thread-safety issues at compile time.

Is it relevant for server-side Swift?

Yes, while heavily used in iOS, these concurrency primitives are core to the Swift language and essential for performant server-side frameworks like Vapor.

Does it support parallel execution?

Absolutely. It covers structured concurrency tools like 'async let' and Task Groups to manage multiple concurrent operations safely.

Implements safe and performant asynchronous Swift code using modern features like async/await, actors, and structured concurrency.

About

This skill equips Claude with the expertise to implement Swift's modern concurrency model effectively. It provides patterns for managing asynchronous tasks without the complexity of completion handlers or the risks of data races. By leveraging actors for state isolation, task groups for parallel execution, and async/await for readable code flow, this skill ensures that Swift applications are both performant and thread-safe. It is particularly useful when refactoring legacy callback-based code or building complex, multi-threaded mobile and server-side applications.
