Swift

Swift is a type of compiled, multi-paradigm, and general-purpose programming language created by the company Apple, with the help of open-source communities. First published in 2015, Swift was regarded as a substitute for Apple's earlier-released programming language called Objective-C. Why? Because Objective-C has barely undergone any change since the 1980s and didn't have many contemporary coding features.

Swift has been working with Coca-Touch and Cocoa frameworks ever since then, and one primary aspect of its layout was the capability to cooperate with massive bodies of preset Objective-C codes created by many Apple products in the last decades.

A few years later, Swift was developed with LLVM compiler frameworks and included in the Xcode since its version 6, published around 2014. On most Apple platforms, it employed Objective-C libraries, allowing C++, C, Object-C, and Swift to operate within one single program.

In 2014, Swift was reintroduced at Apple's Conferences for Worldwide Developers with some latest modifications. It underwent major updates to the 1.2 version in 2014 and then to version 2 in 2015. Originally a type of proprietary language, Swift ver 2.2. was officially turned into an open-source program, accessible to even more users worldwide. Although Swift still pales in comparison to the four options introduced above, it's considered among the most popular by millions of users around the world.
