Zip for combining sequences in Swift - Mini Project: Build & Apply

Zip for combining sequences

📖 Scenario: Imagine you are organizing a small event and you have two lists: one with the names of guests and another with their favorite drinks. You want to pair each guest with their favorite drink to prepare the serving list.

🎯 Goal: Build a Swift program that uses zip to combine two arrays: one with guest names and one with their favorite drinks, then print each guest with their drink.

📋 What You'll Learn

Create an array called guests with these exact names: "Alice", "Bob", "Charlie"

Create an array called drinks with these exact drinks: "Coffee", "Tea", "Juice"

Use zip to combine guests and drinks

Use a for loop with variables guest and drink to iterate over the zipped pairs

Print each guest and their favorite drink in the format: "Alice likes Coffee"

💡 Why This Matters

🌍 Real World

Combining related lists like names and preferences is common in event planning, data processing, and user interface development.

💼 Career

Understanding how to combine sequences efficiently is useful for software developers working with collections, data transformation, and UI data binding.

1

Create the guests array

Create an array called guests with these exact names: "Alice", "Bob", "Charlie"

Swift

# Create the guests array
// Your code here

Need a hint?

Use square brackets [] to create an array and separate names with commas.

2

Create the drinks array

Create an array called drinks with these exact drinks: "Coffee", "Tea", "Juice"

Swift

let guests = ["Alice", "Bob", "Charlie"]
# Create the drinks array
// Your code here

Need a hint?

Use the same array syntax as for guests.

3

Use zip to combine guests and drinks

Use zip to combine guests and drinks into a variable called guestDrinkPairs

Swift

let guests = ["Alice", "Bob", "Charlie"]
let drinks = ["Coffee", "Tea", "Juice"]
# Combine guests and drinks using zip
// Your code here

Need a hint?

Use zip(guests, drinks) and assign it to guestDrinkPairs.

4

Print each guest with their favorite drink

Use a for loop with variables guest and drink to iterate over guestDrinkPairs. Inside the loop, print each guest and their drink in the format: "Alice likes Coffee"

Swift

let guests = ["Alice", "Bob", "Charlie"]
let drinks = ["Coffee", "Tea", "Juice"]
let guestDrinkPairs = zip(guests, drinks)
# Print each guest with their favorite drink
// Your code here

Need a hint?

Use string interpolation with \(variable) inside print.
