What is Swift? Nedir?
Swift is a modern programming language developed by Apple for iOS, macOS, and other Apple platforms.
Swift was introduced at Apple's WWDC conference in 2014, designed to replace Objective-C. Led by Chris Lattner, Swift was positioned as a safe, fast, and expressive language. Type safety and memory safety are paramount in Swift's design. Optional types enable safe handling of nil values, and ARC (Automatic Reference Counting) automates memory management. Playgrounds allow interactive code experimentation. SwiftUI provides declarative UI development, Swift Package Manager handles dependency management, and Swift Concurrency (async/await, actors) offers modern concurrent programming support. Frameworks like Vapor and Kitura enable server-side Swift development. Swift is now the de facto standard language for Apple ecosystem development. The vast majority of new apps on the App Store are developed in Swift. All of Apple's new APIs and frameworks are designed Swift-first.
Use Cases
iOS app development, macOS app development, watchOS and tvOS applications, Server-side development, Systems programming
Pros
Modern and safe language design, Full integration with Apple ecosystem, Objective-C interoperability, High performance, Rapid UI development with SwiftUI
Cons
Largely tied to Apple platforms, ABI stability came late, Limited Linux support, Language keeps changing (breaking changes)
