Swift Playgrounds: Your First App!

Have you ever wondered how apps for iPhone or iPad are made? With Swift Playgrounds, you can learn exactly that — right on the iPad! You’ll learn Swift, the programming language real professionals at Apple use to build their apps. Don’t worry, getting started is easier than you think.

What is Swift Playgrounds?

Swift Playgrounds is a free app from Apple that lets you learn to program. What makes it special:

• You solve puzzles and challenges in a 3D world
• You learn the real programming language Swift (not just blocks!)
• By the end, you can even build your own apps
• There are guided tutorials that walk you through step by step

What you need

• An iPad (iPad Air 3 or newer) or a Mac
• The Swift Playgrounds app (free on the App Store)
• No programming experience needed!

Step 1: Install and open the app

1. Open the App Store on your iPad
2. Search for “Swift Playgrounds”
3. Install the app (it’s free!)
4. Open Swift Playgrounds

Step 2: Solve the first puzzles

Start with the course “Learn to Code 1”:

1. You’ll see a 3D world with a small character named Byte
2. Your task: guide Byte to the gems and switches
3. You do this by typing in commands:
   • moveForward() — Byte takes a step forward
   • turnLeft() — Byte turns left
   • collectGem() — Byte collects a gem
   • toggleSwitch() — Byte presses a switch

Here’s what your first program looks like:

moveForward()
moveForward()
moveForward()
collectGem()

Type in the commands and press “Run My Code” — then watch Byte move!

Step 3: Getting to know loops

At some point it gets tedious to keep typing moveForward() over and over. That’s why there are loops:

for i in 1...5 {
    moveForward()
}
collectGem()

This means: “Move forward 5 steps, then collect the gem.” Much shorter than writing moveForward() five times!

Step 4: Understanding conditions

Sometimes Byte has to make decisions. That’s what if statements are for:

moveForward()
if isOnGem {
    collectGem()
}

This means: “Take a step. If you’re standing on a gem, collect it.” Your program now reacts to the situation!

Step 5: Creating functions

If you need the same steps over and over, you can write your own function:

func turnAndCollect() {
    turnLeft()
    moveForward()
    collectGem()
}

turnAndCollect()
turnAndCollect()
turnAndCollect()

You just invented your own command! That’s exactly how real programmers think.

What comes next?

Once you’ve made it through the basic courses, things get really exciting:

• “Learn to Code 2” — more complex programs with variables and arrays
• “Building Apps with SwiftUI” — build your first real app with buttons, images, and animations!
• “Your Own Projects” — let your creativity run free

Important Swift terms

Why learn Swift?

Swift is the programming language used to build every iPhone and iPad app. If you know Swift, you can eventually publish your own apps on the App Store — how cool would that be? And best of all: the basics you learn in Swift Playgrounds also help you with other programming languages.
