Who Uses Swift? Companies That Use Swift and What Swift Is Used For

David Munyaka - February 04, 2022

Swift offers an exceptional way to write software, whether it’s for desktop computers, mobile phones, or servers. Introduced back in 2014 by Apple, Swift has already become one of the most popular languages for software development environments as it made it easier for developers to build apps for Apple’s products. Apple’s mobile operating system (iOS), accounts for over 59 percent of the total market share in the US alone.

For this reason, Apple decided to create a language that would cater to its products and enhance customer experience. As an aspiring iOS developer, it would be best to learn this programming language to increase your chances of finding a job with a top company. This article covers everything about this programming language, including who uses Swift and the most well-known companies that hire Swift experts.

What Is Swift?

Swift is a general-purpose programming language developed by Apple. This robust language was designed to build apps for Apple products, including iOS, the Apple Watch, Apple TV, and the Mac. Initially, Objective-C was the best language that was integrated into Apple’s products.

However, since it was developed in the 1980s, it became outdated by 2014. So, Apple decided to create a new language with a wider range of features. This made the development process easier as programs ran quicker.

Swift was introduced by Apple and quickly became one of the world’s most popular programming languages. Below you will find a list containing some important statistics regarding Swift’s popularity.

  • Swift was introduced by Apple . This programming language was created by Apple in 2014 with the goal of making it the best language for desktop apps, cloud services, and systems programming.
  • Swift is a popular programming language . Swift climbed up three places in TIOBE’s programming languages index, despite Python’s dominance. Swift was ranked tenth in the world’s most popular programming languages at the time of writing this article.
  • Swift is one of the most used languages . Swift is a favorable programming language for developers. According to Statista, Swift was in the top 20 most used programming languages in 2021 among software developers worldwide.

What Is Swift Used For?

Swift is mainly used for developing mobile and desktop applications of Apple’s devices. Although that is one of its primary functions, Swift was created to make writing, maintaining, and correcting programs easier for developers. Other examples of where this language is used can be found below.

macOS Development

macOS is Apple’s operating system for its desktops and computers. Although iOS development is still the most popular use for Swift, many people prefer using laptops and computers for work and entertainment. Technically, you can still create apps using Objective-C as it shares some common processes with Swift, but many developers today prefer using Swift instead.

iOS Development

Although you can apply powerful languages to the development process, Swift and Objective-C work seamlessly with iOS. Most developers prefer Swift as it contains all the modern code features that make programming easier compared to the existing Objective-C codebase.

Swift is 2.6 times faster than Objective-C and up to 8.4 times faster than Python version 2.7. This makes it the better choice for programming. With an increasing number of people accessing the Internet through iPhones, having a mobile presence is necessary. In addition, if you’re an aspiring iOS developer, you should know that mastering Swift is essential if you want to start a career in this field.

Web Services and Applications

In 2016, Apple made Swift available to Windows and Linux. As a result, Swift is now a cross-platform programming language that can be used to create web services or even web applications. Popular websites such as Medium have tutorials showing how you can build your own app in Swift
