Swift Best Practices

Apply official Swift API Design Guidelines and community best practices when writing, reviewing, or auditing Swift codebases.

Scope boundaries

This skill covers core Swift language fundamentals. It does not cover:

• Concurrency (async/await, actors, Sendable, tasks) — use swift-concurrency.
• SwiftUI (views, state management, layout, animations) — use swiftui-expert-skill.

When a topic touches a boundary (e.g., memory management in tasks, testing async code), defer to the specialized skill and cross-reference it.
