How Swift compiles to native code - Try It Yourself

How Swift compiles to native code

📖 Scenario: Imagine you want to create a simple Swift program that adds two numbers and shows the result. This project will help you understand how Swift code is written and then compiled into native code that your computer can run directly.

🎯 Goal: You will write a Swift program that adds two numbers, set up a variable for the sum, and print the result. This shows the basic steps Swift takes before turning your code into native machine instructions.

📋 What You'll Learn

Create two integer variables with exact values

Create a variable to hold the sum of these two numbers

Add the two numbers and store the result in the sum variable

Print the sum to the console

💡 Why This Matters

🌍 Real World

Adding numbers is a basic task in many apps, like calculators or financial software.

💼 Career

Understanding how Swift code turns into native code helps you write efficient apps for iPhones and Macs.

1

Create two integer variables

Create two integer variables called numberOne and numberTwo with values 7 and 5 respectively.

Swift

# Create two integer variables numberOne and numberTwo with values 7 and 5
// Your code here

Need a hint?

Use var to create variables and assign the numbers 7 and 5.

2

Create a variable to hold the sum

Create a variable called sum and set it to 0 to prepare for storing the addition result.

Swift

var numberOne = 7
var numberTwo = 5
// Create a variable sum and set it to 0
// Your code here

Need a hint?

Initialize sum with 0 before adding the numbers.

3

Add the two numbers and store the result

Add numberOne and numberTwo and assign the result to the variable sum.

Swift

var numberOne = 7
var numberTwo = 5
var sum = 0
// Add numberOne and numberTwo and assign to sum
// Your code here

Need a hint?

Use the + operator to add the two variables and store the result in sum.

4

Print the sum

Use print(sum) to display the value of sum on the console.

Swift

var numberOne = 7
var numberTwo = 5
var sum = 0
sum = numberOne + numberTwo
// Print the sum
// Your code here

Need a hint?

Use the print function to show the sum on the screen.
