About Swift

Swift is Apple’s love letter to modern developers. Launched in 2014 as a successor to aging Objective-C, it combines the power of a compiled language with a syntax that is both readable and easy to write. Swift is designed to be safe, fast, and intuitive - ideal for building apps for iOS, macOS, watchOS, and tvOS. With features like type inference, optionals, and protocol-oriented programming, it appeals to both newcomers and seasoned engineers.

But Swift is not limited to Apple devices. Since going open source in 2015 it has expanded to Linux and Windows, and there are even efforts to use it on Android. Swift is also used on the server side with frameworks like Vapor and SwiftNIO, enabling you to write both frontend and backend in the same language. Tools like Swift Playgrounds and Xcode Playgrounds make learning playful - coding has rarely been this fun.

So whether you want to build the next great iOS app, create a fast server solution, or simply explore a language that blends modern design with practical usability, Swift is an excellent choice.
