Swift Arrays Tutorial 🎯

Welcome to our Swift Arrays tutorial! In this comprehensive guide, we'll dive deep into one of Swift's fundamental data structures - Arrays. We'll cover everything from the basics to advanced usage, making it suitable for both beginners and intermediates. Let's get started!

What is an Array? 📝

An Array is a collection of items stored in contiguous memory locations, allowing us to access them using a single variable name and an index. Arrays are versatile and widely used in programming, making them an essential tool in your Swift toolbox.

Creating an Array in Swift 💡

Creating an Array in Swift is straightforward. Here's how to create a simple Array:

In this example, we've created an Array called fruits and filled it with three strings. The square brackets [] indicate that we're dealing with an Array, and the items are separated by commas.

Accessing Array Elements 💡

To access an Array element, you can use the index number inside square brackets:

In this example, fruits[0] returns the first element in the Array, which is "Apple".

Adding Elements to an Array 💡

You can add elements to an Array using the append(_:) method:

After adding "Mango", our fruits Array now looks like this:

Swift Array Types 📝

Swift supports two types of Arrays:

1. Immutable Arrays: Arrays that cannot be modified once they're created. These are denoted by the let keyword.
2. Mutable Arrays: Arrays that can be modified after they're created. These are denoted by the var keyword.
