Use var to create a variable and assign the exact string.

2

Add a platform name variable

Create a variable called platform and set it to the string "Apple and beyond"

Swift

var welcomeMessage = "Welcome to Swift programming!"
// Create a variable called platform and set it to "Apple and beyond"
// Your code here

Need a hint?

Use var to create the platform variable with the exact string.

3

Combine message and platform using string interpolation

Create a variable called fullMessage that combines welcomeMessage and platform using string interpolation in the format: "Welcome to Swift programming! for Apple and beyond"

Swift

var welcomeMessage = "Welcome to Swift programming!"
var platform = "Apple and beyond"
// Create fullMessage using string interpolation combining welcomeMessage and platform
// Your code here

Need a hint?

Use \(variableName) inside the string to insert variable values.

4

Print the combined message

Use print to display the value of fullMessage

Swift

var welcomeMessage = "Welcome to Swift programming!"
var platform = "Apple and beyond"
var fullMessage = "\(welcomeMessage) for \(platform)"
// Print the fullMessage variable
// Your code here

Need a hint?

Use print(fullMessage) to show the message on the screen.
