How do I use lazy collections for performance in Swift?

Lazy collections in Swift are a powerful way to manage performance when dealing with large datasets. They allow you to compute values only when they're needed, reducing memory usage and potentially enhancing performance.

Example of Lazy Collections in Swift

Below is an example demonstrating how to use lazy collections with Swift's `map` function:


    let numbers = [1, 2, 3, 4, 5]
    let lazyNumbers = numbers.lazy.map { $0 * 2 }
    
    for number in lazyNumbers {
        print(number) // Prints 2, 4, 6, 8, 10
    }
