Swift in VSCode: Create a List of 5 Random Numbers

In this example, you'll learn how to generate a list of five random integers using Swift, all within the VSCode environment. This approach demonstrates how to use Swift's built-in random number generation and array handling to create and print a collection of random values efficiently.

Code

import Foundation

// Create an array of 5 random integers between 1 and 100
let randomNumbers = (1...5).map { _ in Int.random(in: 1...100) }

// Print the array of random numbers
print("Random numbers: \(randomNumbers)")

Key Points

• Use the map function on a range to generate a fixed-size array of random values.
• Int.random(in:) provides a convenient way to generate random integers within a specified range.
• Swift arrays can be initialized and manipulated concisely using functional programming techniques.
• VSCode supports Swift development with proper extensions, enabling easy code writing and execution.
