Welcome back! In the previous lesson, we delved into while loops and how they allow you to execute a block of code as long as a certain condition holds true. Now, we're going to take things a step further by exploring nested loops.

Nested loops involve placing one loop inside another. These are particularly useful for performing more complex operations, such as conducting multiple tasks on multiple items. Mastering nested loops will enhance your ability to handle multifaceted tasks efficiently in Swift.

In this lesson, you'll see how to use nested for loops to iterate over multiple collections simultaneously.

Here's an example that highlights the concept of nested loops:

We'll dissect this example to understand how and when you might use nested loops.

Mastering nested loops opens up a new realm of possibilities in programming. Whether you're processing multi-dimensional data, performing nested iterations, or handling complex scenarios in game development and simulations, nested loops are invaluable. They allow you to write concise and efficient code that can manage intricate tasks with ease.

By the end of this lesson, you'll be comfortable with writing and using nested loops, turning complex problems into manageable solutions. Let's dive into the practice section to solidify this powerful concept together. Ready to enhance your coding skills? Let's get started!
