What you'll learn

Extensions allow you to add functionality to a previously existing class, structure, enumeration, or protocol. This gives you the power to add new behavior to your own code, third-party libraries, and even Apple frameworks. While this sounds simple, extensions allow you to up your Swift game and amplify your code in so many ways. In this talk, Neem Serra will explore using extensions to have cleaner code, conform to protocols, add new initializers, and extend protocols.
