# Swift

Swift is Apple's programming language for iOS, macOS, watchOS, and tvOS development. Designed for safety, performance, and modern software design patterns, it combines the best of C and Objective-C.

## Key Concepts

- Optionals and optional chaining
- Protocol-oriented programming
- Value semantics (structs by default)
- Memory management with ARC
- Swift Package Manager

## Common Use Cases

- iOS/macOS applications
- Server-side development (Vapor)
- Game development (SpriteKit)
- Cross-platform with SwiftUI
- System programming

## Best Practices

- Use structs over classes when possible
- Leverage protocol extensions
- Handle optionals safely
- Use Swift Package Manager
- Test with XCTest
