Bool type and logical operators in Swift - Mini Project: Build & Apply

Bool type and logical operators

📖 Scenario: You are creating a simple app that decides if a person can enter a club based on their age and membership status.

🎯 Goal: Build a program that uses Bool values and logical operators to check if a person is allowed to enter the club.

📋 What You'll Learn

Create a Bool variable for membership status

Create an Int variable for age

Use logical operators && and || to decide entry

Print the final decision as a Bool value

💡 Why This Matters

🌍 Real World

This kind of logic is used in apps to check if users meet certain conditions before allowing access.

💼 Career

Understanding Boolean logic and operators is essential for programming decisions and flow control in software development.

1

Create initial variables

Create a Bool variable called isMember and set it to true. Create an Int variable called age and set it to 20.

Swift

# Create a Bool variable called isMember and set it to true
# Create an Int variable called age and set it to 20
# Your code here

Need a hint?

Use var to create variables. Set isMember to true and age to 20.

2

Add age limit variable

Create an Int variable called ageLimit and set it to 18.

Swift

var isMember: Bool = true
var age: Int = 20
# Create an Int variable called ageLimit and set it to 18
# Your code here

Need a hint?

Use var ageLimit: Int = 18 to create the age limit variable.

3

Use logical operators to check entry

Create a Bool variable called canEnter. Set it to true if isMember is true or if age is greater than or equal to ageLimit. Use the logical operators || and >=.

Swift

var isMember: Bool = true
var age: Int = 20
var ageLimit: Int = 18
# Create a Bool variable called canEnter using logical operators
# Your code here

Need a hint?

Use || for OR and >= to compare age with ageLimit.

4

Print the result

Print the value of canEnter using print(canEnter).

Swift

var isMember: Bool = true
var age: Int = 20
var ageLimit: Int = 18
var canEnter: Bool = isMember || age >= ageLimit
# Print the value of canEnter
# Your code here

Need a hint?

Use print(canEnter) to show the result.
