String is a value type behavior in Swift - Mini Project: Build & Apply

String is a value type behavior

📖 Scenario: Imagine you have a note-taking app where you copy text from one note to another. You want to see how changing the copied text does not affect the original note.

🎯 Goal: You will create two string variables, copy one to the other, change the copy, and see that the original stays the same. This shows how strings behave as value types in Swift.

📋 What You'll Learn

Create a string variable called originalNote with the value "Remember to buy milk".

Create a string variable called copiedNote and assign it the value of originalNote.

Change copiedNote to "Remember to buy milk and eggs".

Print both originalNote and copiedNote to show they are different.

💡 Why This Matters

🌍 Real World

Understanding value types helps you manage data safely in apps like note-taking, messaging, or any place where you copy and change text.

💼 Career

Many Swift jobs require knowing how value types work to write bug-free and efficient code.

1

Create the original string variable

Create a string variable called originalNote and set it to "Remember to buy milk".

Swift

# Create a string variable called originalNote with the value "Remember to buy milk"
# Your code here

Need a hint?

Use var to create a variable and assign the exact text inside double quotes.

2

Copy the original string to a new variable

Create a string variable called copiedNote and assign it the value of originalNote.

Swift

var originalNote = "Remember to buy milk"
# Create a string variable called copiedNote and assign it originalNote
# Your code here

Need a hint?

Assign originalNote to copiedNote using =.

3

Change the copied string

Change the value of copiedNote to "Remember to buy milk and eggs".

Swift

var originalNote = "Remember to buy milk"
var copiedNote = originalNote
# Change copiedNote to "Remember to buy milk and eggs"
# Your code here

Need a hint?

Assign the new string value directly to copiedNote.

4

Print both strings to see the difference

Print originalNote and copiedNote using two separate print statements.

Swift

var originalNote = "Remember to buy milk"
var copiedNote = originalNote
copiedNote = "Remember to buy milk and eggs"
# Print originalNote
# Print copiedNote
# Your code here

Need a hint?

Use print(originalNote) and print(copiedNote) to show both values.
