SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the common pitfalls and outdated patterns LLMs generate for Swift code, particularly concerning the significant changes in Swift 6.2's concurrency model and modern UI frameworks.

Core Features & Use Cases

  • Concurrency Correction: Ensures correct usage of @MainActor, @concurrent, nonisolated, and structured concurrency.
  • Modern UI Patterns: Guides the use of @Observable over ObservableObject for SwiftUI.
  • Performance Primitives: Introduces InlineArray and Span for optimized memory management.
  • Use Case: Generate Swift code for a new macOS app feature, ensuring all asynchronous operations are handled correctly with the latest concurrency features and UI state management is up-to-date.

Quick Start

Generate a Swift 6.2 compatible data model using the @Observable macro for state management.

FAQPage Schema
How do I fix Swift 6.2 concurrency errors in my iOS app?

Swift 6.2 concurrency errors are corrected by applying modern patterns like `@MainActor`, `nonisolated`, and structured concurrency to ensure safe asynchronous operations. This Skill guides proper actor isolation and concurrent code design for iOS.

What's the best way to manage SwiftUI state with the @Observable macro?

The best way to manage SwiftUI state is adopting the `@Observable` macro over `ObservableObject` for modern data model integration. This Skill provides correct Swift 6.2 patterns to update UI state efficiently.

When do I need structured concurrency in macOS app development?

You need structured concurrency in macOS development when handling asynchronous operations to prevent data races and ensure safe execution. This Skill provides correct Swift 6.2 patterns for structured concurrency and modern error handling.

Does Swift 6.2 support performance primitives for optimized memory management?

Yes, Swift 6.2 supports performance primitives like `InlineArray` and `Span` for optimized memory management. This Skill introduces these primitives to optimize performance-critical paths in your code.

Why does my LLM-generated Swift code have outdated class and struct designs?

LLM-generated Swift code often uses outdated patterns because models lack the latest Swift 6.2 concurrency paradigm updates. This Skill corrects common LLM mistakes in class and struct design, async code, and performance paths.
