Swift is friendly to new programmers. The first public release of Swift was released in 2010. Swift is a fantastic way to write software, whether it’s for phones, desktops, servers, or anything else that runs code.It’s an industrial-quality programming language that’s as expressive and enjoyable as a scripting language. 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.Now the latest version of Swift 4, it  is a new programming language developed by Apple Inc for iOS and OS X development. Swift 4 adopts the best of C and Objective-C, without the constraints of C compatibility.

It took Chris Lattner almost 14 years to come up with the first official version, and later, it was supported by many other contributors. Swift 4 has been included in Xcode 6 beta.

Swift 4 is developed by Apple Inc for ios and os X development. Swift 4 adopts the best of C and objective-C without the constraints of C compatibility. Swift 4 uses the same runtime as the existing Obj-C system on Mac OS and iOS, which enables Swift 4 programs to run on many existing iOS 6 and OS X 10.8 platforms.

Swift 4 makes use of Safe programming pattern

Swift 4 provides objectives-C like syntax

Swift 4 is a superb way to write ios and os X apps

Swift 4 does not need a separate library import to support functionalities like input/output or string handling.

Swift UI/Ux developers took ideas from various other popular languages such as Objective-C, Rust, Haskell, Ruby, Python, C#, and CLU.

At WWDC21, Apple announced Swift-DocC, a new documentation compiler for Swift frameworks and packages.  It supports API docs authored as code comments, long-form conceptual articles written in Markdown, and even step-by-step tutorials with integrated images.Swift-DocC provides an effortless way to author great documentation alongside your code, and generate comprehensive documentation websites for Swift codebases.
