What problem does it solve?

This Skill helps you produce correct, idiomatic Swift by guiding you on optionals, value/reference semantics, concurrency, error handling, and Swift Package Manager structure.

Core Features & Use Cases

• Optionals made safe: choose if let/guard let, apply ??, and avoid production force-unwraps.
• Correct types for the job: use struct by default, class only for identity/inheritance/interop, and actor for shared mutable state.
• Concurrency and reliability: structure async/await with cancellation, enforce Sendable, and use throws or Result at appropriate boundaries.
• Swift-idiomatic design: prefer protocol-oriented modeling with any vs some, and use result builders for DSL-like construction.

Quick Start

Ask the AI to refactor your Swift code to use guard let, replace force-unwraps with safe optional handling, and convert shared mutable state into an actor that is safely usable across async tasks.
