Does it provide guidance on migrating from GCD?

Yes, the skill includes patterns for transitioning from legacy Grand Central Dispatch (GCD) and completion handlers to modern structured concurrency.

How does it handle thread safety?

It utilizes Swift Actor patterns and Sendable protocol enforcement to ensure that mutable state is accessed safely across different concurrency contexts.

Can I use this for complex data streaming?

Absolutely. It provides implementation guides for AsyncSequence and AsyncStream, which are ideal for handling web sockets, location updates, or any continuous data flow.

What does the Modern Swift Concurrency Patterns skill do?

It provides Claude with standardized, best-practice implementation patterns for Swift's modern concurrency model, helping you write cleaner async/await code, manage thread safety with actors, and handle parallel tasks.

Can this skill help with SwiftUI and UIKit development?

Yes, it includes specific patterns for @MainActor to ensure that UI updates from background tasks are always handled correctly on the main thread in both SwiftUI and UIKit.

Mobile Development

Provides standardized patterns and implementation guides for modern Swift concurrency including async/await, actors, and structured concurrency for iOS and tvOS.

概要

This skill equips Claude with specialized knowledge of the modern Swift concurrency model, enabling it to write safer, more efficient asynchronous code for iOS and tvOS applications. It covers essential patterns for async/await, actor-based thread safety, parallel execution via TaskGroups, and proper UI state management using @MainActor. It is an indispensable resource for developers migrating from legacy Grand Central Dispatch (GCD) or architecting high-performance mobile apps that require robust state management and non-blocking background operations.
