Swift Programming - 4.0.3 (Ref

- Updated to latest Swift 4.0.3 ------------------------------------------------- Swift is a new multi-paradigm, compiled programming language developed by Apple for iOS and OS X development. Swift is a fantastic way to write software, whether it’s for phones, desktops, servers, or anything else that runs code. It’s a safe, fast, and interactive programming language that combines the best in modern language thinking with wisdom from the wider Apple engineering culture and the diverse contributions from its open-source community. The compiler is optimized for performance and the language is optimized for development, without compromising on either. Swift is friendly to new programmers. It’s an industrial-quality programming language that’s as expressive and enjoyable as a scripting language. Writing Swift code in a playground lets you experiment with code and see the results immediately, without the overhead of building and running an app. - Introduced at Apple's developer conference WWDC 2014 - Swift is designed to replace Objective-C - Swift is intended to be more resilient against erroneous code - Uses the Objective-C runtime, allowing Objective-C, Objective-C++ and Swift code to run within a single program For more details on Swift: https://developer.apple.com/swift/
