SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you build maintainable Swift codebases by guiding value-oriented design, protocol composition, and Swift 6 concurrency practices that reduce fragility and race conditions.

Core Features & Use Cases

  • Value- and type-driven architecture: Prefer struct/enum and protocol-oriented composition over reference semantics and deep inheritance to improve clarity and testability.
  • Swift 6 concurrency correctness: Use Sendable, actors, @MainActor, and structured concurrency (async let, TaskGroup) to satisfy strict concurrency checking and prevent unsafe cross-boundary sharing.
  • Pragmatic API, error, and project design: Apply throws/Result, deliberate initializer/factory design, and SPM target structuring to produce predictable, library-quality interfaces.

Quick Start

Ask for a Swift 6 architecture review of a small code snippet, and request a concrete refactor plan using value types, actors where needed, and a Swift Testing strategy for the main logic.

FAQPage Schema
How do I fix Swift 6 concurrency errors and unsafe cross-boundary data sharing?▼

Fix Swift 6 concurrency errors by applying Sendable conformances, actor isolation, and @MainActor usage. Restructure async/await data flow to satisfy strict concurrency checking and eliminate race conditions.

What is the best way to structure a Swift Package Manager project for library-quality APIs?▼

Structure SPM projects by organizing targets deliberately and applying pragmatic initializer or factory design. Combine throws and Result types to produce predictable, library-quality Swift interfaces.

How do I use protocol-oriented programming and value types to improve Swift testability?▼

Use protocol-oriented programming by preferring struct and enum composition over deep class inheritance. This value-driven architecture improves code clarity and testability while reducing fragile reference semantics.

Does Swift Testing work with actor isolation and structured concurrency patterns?▼

Yes, Swift Testing integrates with actor isolation and structured concurrency patterns like async let and TaskGroup. Design tests around value types and isolated actors to validate concurrent logic safely.

When should I use actors versus value types for Swift concurrent state management?▼

Use value types like struct and enum for isolated data passing, and reserve actors for mutable shared state. Apply Sendable conformances to ensure safe concurrent boundaries across typical app workflows.
