SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps teams quickly identify and fix Swift concurrency issues in Swift 6.2+ codebases, improving correctness and performance by addressing actor isolation, data races, and Sendable compliance.

Core Features & Use Cases

  • Review and remediate Swift concurrency usage in codebases targeting Swift 6.2+.
  • Propose minimal, safe fixes for actor-isolation, Sendable conformance, and default actor isolation improvements.
  • Real-world use: Refactor a nonisolated type to conform to a MainActor boundary, or replace data-race-prone patterns with concurrent-safe implementations.

Quick Start

Provide a sample Swift file or project snippet to the Skill and ask to review concurrency usage; the Skill will propose changes and generate a patch or guidance.

FAQPage Schema
How do I fix Swift 6.2 actor isolation compiler errors in my project?

To fix Swift 6.2 actor isolation compiler errors, analyze your codebase to identify nonisolated types and refactor them to conform to MainActor boundaries or apply default actor isolation improvements for data-race safety.

What is the best way to ensure Sendable compliance during a Swift concurrency refactor?

Ensuring Sendable compliance during a Swift concurrency refactor involves reviewing your types and proposing minimal, safe fixes to meet Sendable conformance requirements, preventing data races across concurrent boundaries.

How do I review Swift code for data-race-prone patterns?

Review Swift code for data-race-prone patterns by providing a sample file to analyze concurrency usage, which then proposes changes and generates guidance to replace unsafe implementations with concurrent-safe alternatives.

Can I use this to remediate concurrency issues for a Swift 6.2 migration?

Yes, you can remediate concurrency issues for a Swift 6.2 migration by analyzing project sources against Swift 6.2+ features and reference guidance to address actor isolation and Sendable safety.

Why does my Swift code fail Sendable checks after updating to Swift 6.2?

Swift code fails Sendable checks after updating to Swift 6.2 because the compiler enforces strict concurrency safety, requiring you to review types and apply minimal fixes for Sendable conformance and actor isolation.

What are the limitations of automated Swift concurrency remediation?

Automated Swift concurrency remediation requires access to actual project sources and Swift 6.2+ features to generate patches, meaning it cannot safely propose fixes without analyzing the specific codebase context and isolation boundaries.
