Swift 3 is the first significant release since Apple’s heralded programming language became an open source project in late 2015. In this report, Jon Manning, Paris Buttfield-Addison, and Tim Nugent—authors of Learning Swift—provide a tour of Swift 3 and its growing ecosystem. You’ll learn about the language’s most impactful and interesting new features, and explore Swift’s use on non-Apple platforms.
Many changes in Swift 3 are subtle refinements that knock the rough corners off the language, making human interactions with Swift much smoother. To help you gain a better understanding of Swift 3, the authors provide a simple program designed for one of Apple’s Swift Playgrounds.
