Swift (programming language)

Swift is a general-purpose, multi-paradigm, object-oriented, functional, imperative and block structured language. It is the result of the latest research on programming languages and is built using a modern approach to safety, software design patterns by Apple Inc.. It is the brand new programming language for iOS application, macOS application, watchOS application, tvOS application. Soon it became one of top 5 programming language and gained popularity among Apple developer community over the few years of time replacing the old school Objective C.

Evolution of Swift Programming Language:
Swift language was developed by ‘Chris Lattner‘ with an aim to resolve difficulties existed in Objective C. It was introduced at Apple’s 2014 Worldwide Developers Conference (WWDC) with version Swift 1.0. Soon, It underwent an upgrade to version 1.2 during 2014. Swift 2.0 was introduced at WWDC 2015. Initially, version 2.2 was made open-source software under the Apache License 2.0 on December 3, 2015, for Apple and Linux platforms. It is primarily 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 language has gone through major changes since its release from version names 1.0, 2.0, 3.0 and 4.0 and later. The current released version is Swift 4.2 with a beta version of Swift 4.3 and Xcode 10.


  • Swift is open sourced and easy to learn.
  • Swift is fast, safe and expressive.
  • Swift is approachable and familiar (C and C++ code can be added by Swift programmers into Swift applications.)
  • Swift is the future of Apple development.
  • Swift is enterprise ready.


  • The language is still quite young and talent pool is limited.
  • Swift is considered a “moving target” as it is a new language and number of swift programmers are few.
  • Poor interoperability with third-party tools and IDEs
  • Lack of support for earlier iOS versions.
