SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Swift concurrency is complex; this skill provides structured guidance to reason about actors, isolation, Sendable, task management, and migration to Swift 6.2+. It helps developers navigate concurrency challenges, optimization, and safe cross-thread patterns.

Core Features & Use Cases

  • Guidance on foundational concurrency topics, including async/await basics, actors, Sendable, memory management, and testing.
  • Migration strategies for Swift 6, strict concurrency checking, and progressive adoption of upcoming features.
  • Clear reference routing and best practices to apply concurrency patterns in real-world projects.

Quick Start

Follow the Swift Concurrency Skill to identify, diagnose, and safely migrate concurrency patterns across actors, isolation, and Sendable in real projects.

FAQPage Schema
How do I migrate to Swift 6 strict concurrency checking safely?▼

Migrate to Swift 6 strict concurrency by following structured guidance on progressive adoption, enabling strict concurrency checking incrementally, and applying isolation patterns to ensure safe cross-thread state management.

What is the best way to handle Swift actors and Sendable compliance?▼

Handle Swift actors and Sendable compliance by using structured guidance to reason about actor isolation, ensuring safe cross-thread data passing, and applying memory management best practices for predictable suspension.

How do I test asynchronous flows and actor isolation in Swift?▼

Test asynchronous flows and actor isolation in Swift by applying structured guidance on robust testing patterns for async/await, ensuring predictable suspension and safe state management across concurrent operations.

Can I apply Swift concurrency patterns to network services and SwiftUI apps?▼

Yes, Swift concurrency patterns apply across SwiftUI apps and network services, providing structured guidance on actors, isolation, and Sendable to manage safe state and predictable suspension in real-world projects.

When do I need to use Sendable and actor isolation in Swift?▼

Use Sendable and actor isolation in Swift when managing safe cross-thread state, ensuring predictable suspension, and migrating codebases to strict concurrency models to prevent data races and concurrency violations.
