Repeat-while loop in Swift - Mini Project: Build & Apply

Repeat-while Loop in Swift

📖 Scenario: You are creating a simple program that counts up from 1 until it reaches a certain number. This is like counting steps while walking until you reach your destination.

🎯 Goal: Build a Swift program that uses a repeat-while loop to count from 1 up to a given limit and then prints the final count.

📋 What You'll Learn

Create a variable called count starting at 1

Create a constant called limit with the value 5

Use a repeat-while loop to increase count by 1 until it is greater than limit

Print the final value of count

💡 Why This Matters

🌍 Real World

Counting steps or attempts until a goal is reached is common in games, apps, and devices.

💼 Career

Understanding loops like repeat-while helps in automating repeated tasks and controlling program flow in software development.

1

Create the initial count variable

Create a variable called count and set it to 1.

Swift

# Create a variable called count and set it to 1
# Your code here

Need a hint?

Use var to create a variable and assign it the value 1.

2

Set the limit constant

Create a constant called limit and set it to 5.

Swift

var count = 1
# Create a constant called limit and set it to 5
# Your code here

Need a hint?

Use let to create a constant and assign it the value 5.

3

Use a repeat-while loop to count up

Write a repeat-while loop that increases count by 1 each time, and continues while count is less than or equal to limit.

Swift

var count = 1
let limit = 5
# Write a repeat-while loop to increase count by 1 while count is less than or equal to limit
# Your code here

Need a hint?

Use repeat { ... } while condition syntax. Inside the loop, add 1 to count.

4

Print the final count

Write a print statement to display the value of count.

Swift

var count = 1
let limit = 5
repeat {
    count += 1
} while count <= limit
# Print the value of count
# Your code here

Need a hint?

Use print(count) to show the final number.
