Does it provide guidance on preventing retain cycles?

Yes, it includes specialized logic for ARC and memory management, helping you correctly use weak, unowned, and capture lists in closures.

Does this skill support the latest Swift 6.2 features?

Yes, it specifically includes expertise in Swift 6.2 features like InlineArray, Span types, nonisolated functions, and advanced concurrency safety.

Can it help me migrate from XCTest to the new Swift Testing framework?

Absolutely. It provides standardized patterns for @Test, @Suite, and expectation macros to modernize your testing suite.

How does this skill handle Swift Concurrency challenges?

It offers expert guidance on actor reentrancy, MainActor isolation, and ensuring types are Sendable to pass strict concurrency checks.

Mobile Development

Enables Claude to architect, write, and optimize modern Swift 6.2 applications using structured concurrency, advanced macros, and high-performance patterns.

About

The Swift Language Expert skill transforms Claude into a senior-level Apple platform specialist with deep knowledge of Swift 6.2. It provides precise implementation patterns for modern language features including actor isolation, Sendable safety, and the Swift Testing framework. Beyond simple syntax, this skill guides developers through complex domain-specific challenges such as memory management (ARC), Swift Package Manager (SPM) configuration, and performance optimization using InlineArray and Span types. It is an essential companion for building robust iOS, macOS, and server-side Swift applications that adhere to the latest industry standards.
