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.
