    Swift is a multi-paradigm, compiled programming language created for
     iOS, OS X, watchOS, tvOS and Linux development by Apple Inc. Swift is
     designed to work with Apple's Cocoa and Cocoa Touch frameworks and the
     large body of existing Objective-C code written for Apple products. Swift
     is intended to be more resilient to erroneous code (\"safer\") than
     Objective-C and also more concise. It is built with the LLVM compiler
     framework included in Xcode 6 and later and uses the Objective-C runtime,
     which allows C, Objective-C, C++ and Swift code to run within a single
     program.
