+# Swift Language Prompt Snippet
+
+## Key Concepts
+
+- **Optionals and Optional Chaining**: `Type?` wraps values that may be nil; `?.` chains safely
+- **Protocols and Protocol Extensions**: Define contracts with default implementations via extensions
+- **Value Types vs Reference Types**: Structs and enums are value types; classes are reference types
+- **Closures**: Self-contained blocks of functionality that capture surrounding context
+- **Property Wrappers**: `@State`, `@Binding`, `@Published` encapsulate property storage logic
+- **Result Builders**: `@ViewBuilder`, `@resultBuilder` enable declarative DSL syntax
+- **Actors and Structured Concurrency**: `actor` types for data isolation; `async let`, `TaskGroup`
+- **Generics**: Type parameters with `where` clauses and associated type constraints
+- **Enums with Associated Values**: Each case can carry distinct typed payloads
+- **Extensions**: Add methods, computed properties, and protocol conformance to existing types
+
+## Import Patterns
+
+- `import Foundation` — core library with data types, collections, networking
+- `import UIKit` — iOS UI framework for traditional view controller architecture
+- `import SwiftUI` — declarative UI framework with reactive state management
+- `@testable import ModuleName` — import with internal access for unit testing
+
+## File Patterns
+
+- `Package.swift` — Swift Package Manager manifest defining targets and dependencies
+- `*.xcodeproj` / `*.xcworkspace` — Xcode project and workspace configuration
+- `AppDelegate.swift` — UIKit application lifecycle entry point
+- `App.swift` — SwiftUI application entry point using `@main`
+- `Tests/` — test target directory following SPM or Xcode conventions
+
+## Common Frameworks
+
+- **SwiftUI** — Declarative UI framework with reactive data flow
+- **UIKit** — Imperative UI framework using view controllers and Auto Layout
+- **Vapor** — Server-side Swift web framework with async support
+- **Combine** — Reactive framework for processing values over time
+- **Core Data** — Object graph and persistence framework
+
+## Example Language Notes
+
+> Uses `@Published` property wrapper to automatically notify SwiftUI views of state
+> changes. When the wrapped value mutates, the property wrapper triggers `objectWillChange`
+> on the enclosing `ObservableObject`, causing dependent views to re-render.
+>
+> Protocol extensions provide default implementations, allowing types to conform by
+> simply declaring conformance — no method body needed if defaults suffice.
