*Content taken from Apple Developer: Swift
Swift is a powerful and intuitive programming language for macOS, iOS, watchOS, tvOS and beyond. Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love. Swift code is safe by design, yet also produces software that runs lightning-fast.
In order to download Swift, you must first install xCode, which is available here.
Swift 5 makes it dramatically easier to release your apps. Because the Swift runtime is now built into iOS, macOS, tvOS, and watchOS, your app no longer needs to bundle this library for these latest OS releases. Users who download an app built with Swift from the App Store will get a smaller app and a faster download.
Swift can open doors to the world of coding. In fact, it was designed to be anyone’s first programming language, whether you’re still in school or exploring new career paths. For educators, Apple created free curriculum to teach Swift both in and out of the classroom. First-time coders can download Swift Playgrounds—an app for iPad that makes getting started with Swift code interactive and fun.
