Solved: How do I see which version of Swift I’m using

Swift is a fresh and dynamic programming language invented by Apple. It is fast, safe, modern, and brings about seamless interaction in development. It is a prime choice for iOS, MacOS, WatchOS, and even server-side development. Swift has multiple versions, each with updates and new features. Sometimes, it is necessary to determine which version of Swift you’re operating. Worry not, it’s straightforward to pin down the version you’re utilizing.

Swift’s evolution is nothing short of swift, pun intended. With a plethora of modifications and amendments in each release, it could pose quite a struggle to track the present version. Today, we dive into the nuts and bolts on how to resolve this common problem.

How to verify your version of Swift

Swift provides an easy command to glance at the version currently in use. This can be executed right from the terminal, regardless of whether you are on Linux or Mac. Here’s a step by step guide on how to do it:

  • First, open up the terminal application. It’s located in the Utilities folder inside Applications.
  • Type the command
     swift --version 

    and press enter.

  • The terminal will output information about the currently installed version of Swift. It will show the Swift version, the target, and when it was released.

The terminal application is one of the most potent tools at a developer’s disposal, providing an efficient and precise solution to seeing the Swift version.

The Importance of Swift Libraries

Swift programming language would be half-baked without Swift Package Manager. This tool aids in the management of Swift build dependencies. It doesn’t merely resolve dependencies but simplifies processes such as automated module generation and linking system libraries.

Swift Functions Deep-Dive

Functions are at the core of Swift programming. They’re isolated chunks of code that perform a specific task. Swift functions are unique in that they support default values and variadic parameters. They also produce tuples, making it possible for one function to produce more than one output.

Whether you’re a seasoned Swift developer or a novice, proficiency in Swift’s different versions, usage of libraries, and master of functions is crucial. Remember, ‘swift -version’ is your ticket to discern the currently installed Swift version. Happy coding, and may the Swift force be with you!
