Swift is statically typed, memory-safe, expressive, and increasingly used outside Apple platforms for server-side and systems programming.\n\n## Key language features\n\n  * **Type system.** Static typing with generics, protocols (with associated types), type inference, optionals for null safety.\n  * **Memory model.** Automatic Reference Counting (ARC), no garbage collector; predictable performance.\n  * **Value types.** Structs and enums are first-class with full method support; reference types (classes) are explicit.\n  * **Concurrency.** async/await, actors, structured concurrency, and Sendable protocols since Swift 5.5.\n  * **Swift Package Manager.** Native dependency manager for libraries and applications.\n\n\n\n## Where Swift is used\n\n  * iOS / iPadOS / macOS / watchOS / tvOS / visionOS apps via SwiftUI or UIKit/AppKit\n  * Server-side (Vapor, Hummingbird) and CLI tools\n  * Embedded systems (Swift on embedded MCUs, Embedded Swift)\n  * Cross-platform via Swift on Linux and Windows\n\n\n\n🔗\n\n**Related Terms**\nSwiftUI, iOS, Kotlin, Android\n\n📖\n\n**Further Reading**\nEmbedding Flutter Modules into Native Android and iOS Apps",
