Switch statement power in Swift - Mini Project: Build & Apply

Switch statement power

📖 Scenario: You are creating a simple program to identify the type of a day based on its name. This helps you plan your activities better.

🎯 Goal: Build a Swift program that uses a switch statement to print the type of day (weekday or weekend) for a given day name.

📋 What You'll Learn

Create a variable called day with the exact value "Saturday".

Create a variable called dayType to hold the result.

Use a switch statement on day with cases for weekdays and weekends.

Assign "Weekend" or "Weekday" to dayType inside the switch.

Print the value of dayType.

💡 Why This Matters

🌍 Real World

Switch statements help you make decisions based on different values, like choosing actions for days of the week in scheduling apps.

💼 Career

Understanding switch statements is important for writing clear and efficient code in many programming jobs, especially when handling multiple conditions.

1

DATA SETUP: Create the day variable

Create a variable called day and set it to the string "Saturday".

Swift

# Create a variable called day and set it to "Saturday"
# Your code here

Need a hint?

Use var day = "Saturday" to create the variable.

2

CONFIGURATION: Create the dayType variable

Create a variable called dayType and set it to an empty string "".

Swift

var day = "Saturday"
# Create a variable called dayType and set it to an empty string ""
# Your code here

Need a hint?

Use var dayType = "" to create the variable.

3

CORE LOGIC: Use switch statement to set dayType

Use a switch statement on the variable day. For cases "Monday", "Tuesday", "Wednesday", "Thursday", and "Friday", set dayType to "Weekday". For cases "Saturday" and "Sunday", set dayType to "Weekend". Use a default case to set dayType to "Unknown".

Swift

var day = "Saturday"
var dayType = ""
# Use a switch statement on day to set dayType for weekdays and weekends
# Your code here

Need a hint?

Use commas to group multiple cases in one line inside the switch.

OUTPUT: Print the dayType

Write a print statement to display the value of the variable dayType.

Swift

var day = "Saturday"
var dayType = ""
switch day {
case "Monday", "Tuesday", "Wednesday", "Thursday", "Friday":
    dayType = "Weekday"
case "Saturday", "Sunday":
    dayType = "Weekend"
default:
    dayType = "Unknown"
}
# Print the value of dayType
# Your code here

Need a hint?

Use print(dayType) to show the result.
