SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Swift developers struggle with diagnosing concurrency issues, migrating legacy code to Swift 6, and refactoring callback-based workflows to async/await. This skill provides structured guidance to diagnose issues, plan migrations, and implement safe concurrency patterns.

Core Features & Use Cases

  • Diagnose concurrency issues, identify isolation boundaries, and propose safe fixes for Swift projects.
  • Guide Swift 6 migration, including adoption of nonisolated, @concurrent, and strict concurrency features.
  • Refactor callback-based code to async/await with concrete examples and migration-ready patterns.

Quick Start

Analyze a Swift project to identify concurrency issues, plan a Swift 6 migration, and generate a step-by-step refactor guide replacing callbacks with async/await.

Frequently Asked Questions about swift-concurrency

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

FAQPage Schema
How do I migrate callback-based Swift code to async/await?▼

To migrate callback-based Swift code to async/await, analyze code paths and isolation domains to replace completion handlers with async functions. This process provides concrete examples and migration-ready patterns for safe concurrency refactoring.

What is the best way to diagnose Swift concurrency data races and thread safety issues?▼

Diagnosing Swift concurrency data races involves analyzing isolation boundaries and actor domains to identify thread safety violations. This provides actionable fixes for concurrency-related compiler and linter warnings regarding Sendable conformance.

How do I plan a Swift 6 migration for strict concurrency?▼

Planning a Swift 6 migration requires analyzing project settings and adopting strict concurrency features like nonisolated and @MainActor. This guides the transition by assessing migration impact and implementing safe concurrency patterns.

Why am I getting Swift concurrency warnings when using actors and @MainActor?▼

Swift concurrency warnings involving actors and @MainActor occur when isolation boundaries are crossed unsafely. Analyzing code paths and isolation domains identifies these violations and provides actionable fixes for strict concurrency compliance.

Do I need to understand Swift isolation domains to fix Sendable compiler warnings?▼

Yes, understanding Swift isolation domains is required to fix Sendable compiler warnings. Analyzing how tasks and actors interact allows you to identify data race risks and apply correct Sendable conformances for thread safety.
