What is Swift Code? All Your Questions Answered

As is widely known, there is no bigger name in mobile technology than Apple over the past fifteen years. From the moment Steve Jobs debuted the first iPhone for tech enthusiasts, to the current versions of iPads and iPhones containing technology like facial recognition, fingerprint identification, and professional quality cameras, Apple has been considered the gold standard in mobile technology and applications.

So why is this important? Because if you are looking to learn a new coding language for career opportunities, developing innovative ideas or apps, or reaching a wide audience, then it is a wise decision to learn to be proficient in coding for Apple devices. And that means being proficient in Swift -- the robust and intuitive dedicated programming language used for macOS, iOS, watchOS, tvOs, and the entirety of the Apple programming universe.

Before getting into the exciting opportunities and potential uses for Swift, we will start with the basics -- which is why we created this guide. So if you have been wondering “What is Swift code?” or “What can I use Swift Code for?”, read on and learn the ropes!

So first, what is Swift code anyway?

Unlike some of its older programming language counterparts (such as Javascript or Python), Swift is a relatively new coding language. Originally created during summer of 2010 by Chris Lattner, as part of a collaboration with many other Apple programmers, Swift was designed to build on the best aspects of other existing languages (like Ruby, C#, Python, and many more). 

In true Apple fashion though, the motivation behind Swift was to craft a dedicated programming language specifically designed for the suite of Apple operating systems that would match the rapidly growing demand for new applications, functions, and systems on a variety of Apple products.

Like any other programming language, Swift has evolved through several iterations, with the most recent, Swift 4.1, released in March of 2018. It has often been cited as one of the most popular and favored programming languages by developers around the world, both for its widespread uses and the various related tools (like Swift Sandbox and Swift Playgrounds) that Apple continuously releases to aid developers in honing their craft.

What can I use Swift code for? 

While Android is certainly an equally formidable force in mobile technology and computing, Apple remains the most popular worldwide. Why is this important? Because there has been consistent and reliable demand for new Apple features, applications, and “cool ideas” from dedicated Apple fanatics, a trend that does not appear to be changing anytime soon.

With this in mind, here’s what you can do if you make the wise decision to learn Swift:

  • Swift is open source -- for beginning coders out there, this means that anyone has the ability to inspect, modify, and enhance the existing Swift source code. This matters, because it makes the language easier to adopt and innovate with, backed up by Swift’s consistent ranking among the Top 10 most used programming languages in the world.
  • Much like Python, Swift was designed for ease-of-use and with simplicity in mind, making it one of the easiest coding languages to learn. While there are different levels of knowledge needed to truly start developing robust apps and ideas, people can often become proficient with Swift in just a few short months.
  • Apple wants you to learn it and use it -- this is supported not only by the variety of developer tools Apple is continually releasing, but also reflected by Apple’s dedication to the language as the backbone of future development.
  • Swift is also enterprise-ready -- unlike some other programming languages, Swift’s open source nature means it can be used not only for Apple, but also for Linux and Android. This is perfect for developers creating client/server solutions, and opens up an even wider range of development possibilities.

So why should I learn Swift?

There are so many use cases (both proven and theoretical) for Swift that simply outlining those alone are a reason to consider taking a Swift 4 course. However, there are also a few practical reasons for both beginning and intermediate developers considering adding Swift programming skills to their knowledge base:

  • For starters, Apple is Apple. There’s a reason that a new iPhone, iPad, or Macbook seems to emerge every few months -- demand. With hundreds of millions of dedicated users and product loyalists around the globe, the need for new Swift developers is not only already in existence, but promises to be an ongoing demand. There will always be opportunities for work and new projects if you are fluent in Swift.
  • This demand goes beyond job opportunities, and into pay as well. With companies around the world competing for qualified and creative Swift programmers, the pay rates for skilled Swift developers are very high. Swift adds both a lucrative skill and a resume booster to your portfolio.
  • The opportunities for creativity and experimentation with Swift are second to none -- be it through the use of tools like Swift Sandbox or by simply messing around with the source code once you have honed your skills. The flexibility and opportunity to make your own mark with Swift makes it an exciting programming language for innovative minds.
