Get ready to embark on an exciting journey into the world of Swift programming! In this article, we’ll take you by the hand and show you how to create a simple yet iconic “Hello, World!” program in Swift.
What’s the Big Deal About “Hello, World!”?
This program is more than just a few lines of code – it’s a rite of passage for beginners. It’s a way to introduce yourself to a new programming language and get a feel for how it works. And, let’s be honest, there’s something special about seeing those two words pop up on your screen for the first time!
Before We Begin

The Anatomy of a Swift “Hello, World!” Program
So, what makes this program tick? Let’s break it down into its component parts:
Comments: The Unsung Heroes
In Swift, we use two slashes // to write comments. These are notes to ourselves (and others) that help make our code more readable and understandable. Think of them as little reminders that explain what our code is doing.
The Print Statement: Bringing It All to Life
The print statement is the magic that makes our program display “Hello, World!” on the screen. It’s a simple yet powerful tool that helps us communicate with the user.
