SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It helps developers automatically review Swift source code for concurrency correctness, modern API usage, and common async/await pitfalls, reducing manual inspection effort and preventing subtle race conditions.

Core Features & Use Cases

  • Reference‑driven analysis: Scans code against curated hotspot lists, new Swift 6.2 features, and known bug patterns.
  • Actor and task validation: Checks actor reentrancy, structured vs. unstructured task usage, and proper cancellation handling.
  • Async stream and bridging checks: Ensures correct use of AsyncStream, continuations, and legacy API wrappers.
  • Diagnostics mapping: Interprets strict‑concurrency compiler errors and suggests concrete fixes.
  • Testing guidance: Provides recommendations for async test design and cancellation testing.

Quick Start

Ask the Swift Concurrency Pro skill to review the file DataLoader.swift for concurrency issues.

FAQPage Schema
How do I detect async/await concurrency bugs in Swift code?

To detect async/await concurrency bugs in Swift code, scan source files against curated hotspot lists and known bug patterns. This process automatically identifies subtle race conditions and common async/await pitfalls.

What are common Swift actor reentrancy and task cancellation issues?

Common Swift actor reentrancy and task cancellation issues involve improper structured versus unstructured task usage and missing cancellation handling. Checking actor reentrancy ensures correct task management and prevents unexpected state mutations.

How do I fix strict-concurrency compiler errors in Swift?

To fix strict-concurrency compiler errors in Swift, map the diagnostics to concrete code fixes. Interpreting these compiler errors helps correct modern API usage and resolve async stream bridging problems accurately.

Does this Swift concurrency review support AsyncStream and legacy API wrappers?

Yes, this Swift concurrency review supports AsyncStream and legacy API wrappers. It ensures correct use of continuations and validates that legacy API wrappers are bridged properly without introducing race conditions.

What is the best way to test async cancellation in Swift?

The best way to test async cancellation in Swift is to follow specific testing guidance for async test design. This approach validates proper cancellation handling and ensures structured task management behaves correctly.

Can I use this to review Swift 6.2 concurrency features in my codebase?

Yes, you can use this to review Swift 6.2 concurrency features in your codebase. The analysis scans code against new Swift 6.2 feature guides to verify modern API usage and concurrency correctness.
