Tuples for grouped values in Swift - Mini Project: Build & Apply

Tuples for grouped values

📖 Scenario: You are organizing a small fruit shop's inventory. Each fruit has a name and a price per kilogram. You want to group these two pieces of information together for easy handling.

🎯 Goal: Build a Swift program that uses tuples to group fruit names with their prices, then access and display this grouped information.

📋 What You'll Learn

Create a tuple with a fruit name and its price

Create a second tuple with another fruit name and price

Access tuple elements by name

Print the fruit name and price in a friendly message

💡 Why This Matters

🌍 Real World

Grouping related data like fruit name and price helps organize inventory information clearly and accessibly.

💼 Career

Understanding tuples is useful for developers to group small sets of related data without creating full custom types.

1

Create the first fruit tuple

Create a tuple called fruit1 with two named elements: name set to "Apple" and price set to 2.5.

Swift

# Create the tuple fruit1 with name "Apple" and price 2.5
# Your code here

Need a hint?

Use let fruit1 = (name: "Apple", price: 2.5) to create the tuple with named elements.

2

Create the second fruit tuple

Create a tuple called fruit2 with two named elements: name set to "Banana" and price set to 1.2.

Swift

let fruit1 = (name: "Apple", price: 2.5)
# Create the tuple fruit2 with name "Banana" and price 1.2
# Your code here

Need a hint?

Use the same tuple syntax as before but with the new values.

3

Access tuple elements

Create two constants called firstFruitName and secondFruitPrice. Set firstFruitName to the name element of fruit1. Set secondFruitPrice to the price element of fruit2.

Swift

let fruit1 = (name: "Apple", price: 2.5)
let fruit2 = (name: "Banana", price: 1.2)
# Access fruit1's name and fruit2's price into constants
# Your code here

Need a hint?

Use dot notation like fruit1.name to get the element from the tuple.

4

Print the fruit information

Print a message using print that says: "The first fruit is Apple and the second fruit costs 1.2 dollars per kg." Use the constants firstFruitName and secondFruitPrice inside the message with string interpolation.

Swift

let fruit1 = (name: "Apple", price: 2.5)
let fruit2 = (name: "Banana", price: 1.2)
let firstFruitName = fruit1.name
let secondFruitPrice = fruit2.price
# Print the message using print and string interpolation
# Your code here

Need a hint?

Use print("The first fruit is \(firstFruitName) and the second fruit costs \(secondFruitPrice) dollars per kg.").
