Swift Language Patterns

Core Swift language features and modern syntax patterns targeting Swift 6.3. Covers language constructs, type system features, Codable, string and collection APIs, formatting, C interop (@c), module disambiguation (ModuleName::symbol), and performance attributes (@specialized, @inline(always)). For concurrency (actors, async/await, Sendable), see the swift-concurrency skill. For SwiftUI views and state management, see swiftui-patterns.
