In the previous chapters, you&rsquo;ve mastered the building blocks of Swift: types, functions, control flow, and managing optional values. You&rsquo;ve learned how to create your own custom structures and classes, giving you powerful tools to model your data.</p> <p>But what if you want to add new capabilities to a type you <em>didn&rsquo;t</em> create? Or perhaps you want to organize your own type&rsquo;s functionality into more manageable, thematic chunks? That&rsquo;s where <strong>Extensions</strong> come in! Extensions are a super cool feature in Swift that allow you to add new functionality to an existing class, structure, enumeration, or even a protocol type, <em>without</em> modifying the original type definition. Think of it like adding extra pockets to your favorite jacket – you&rsquo;re not changing the jacket itself, just making it more useful!</p>
