SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the complexity of managing concurrency in Swift by providing patterns and best practices for actor isolation, safe conformances, and background execution.

Core Features & Use Cases

  • Actor-safe concurrency patterns: Guides developers on adopting Swift 6.2's concurrency model to prevent data races.
  • Explicit background work: Explains how to offload CPU-heavy tasks using @concurrent.
  • Use Case: A developer is refactoring a Swift app to improve thread safety by applying new Swift 6.2 concurrency features, ensuring code runs only on the main thread unless explicitly offloaded.

Quick Start

Use the Swift concurrency skills to implement actor-safe code patterns in your project.

Frequently Asked Questions about swift-concurrency-6-2

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement actor isolation in Swift to prevent data races?▼

Actor isolation in Swift prevents data races by restricting property and method access to a single execution context. This Skill provides patterns for adopting Swift 6.2's concurrency model to ensure safe, modern code execution.

How do I offload CPU-heavy tasks to a background thread in Swift 6.2?▼

You can offload CPU-heavy tasks using the `@concurrent` attribute for explicit background execution. This Skill explains how to apply this feature, ensuring code runs on the main thread unless explicitly offloaded.

What is the best way to migrate an app to Swift 6.2 concurrency?▼

Migrating to Swift 6.2 concurrency involves adopting actor-safe patterns and explicit background execution. This Skill guides developers through refactoring apps to improve thread safety using new concurrency features.

Does Swift 6.2 concurrency support protocol conformances with actors?▼

Yes, Swift 6.2 concurrency supports safe protocol conformances within actor-isolated contexts. This Skill provides guidance on adopting the concurrency model with actor safety and proper protocol conformances.

When should I use @MainActor versus explicit background execution in Swift?▼

Use @MainActor for UI updates and explicit background execution for CPU-heavy tasks. This Skill outlines patterns to ensure code runs only on the main thread unless explicitly offloaded using `@concurrent`.
