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.
