Overview
Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS, and Linux. Apple intended Swift to support many core concepts associated with Objective-C, but in a “safer” way, making it easier to catch software bugs. Swift was introduced in 2014.[1]
Swift is a popular programming language for the Apple platforms it supports, but it lacks support for Microsoft Windows environments.[2].
Example
Hello World
// This program displays "Hello world!"
//
// References:

print("Hello world!")
Output
Hello world!
Discussion
