This book gives you an introduction to the programming language, Swift. Swift is a fairly new programming language (version 1 came out in September 2014) and the language can be used to write programs for most of the Apple devices, including the iPhone, iPad, Apple Watch, MacBook, and Apple TV. Throughout the book, we will gradually introduce you to more and more programming concepts until we have enough knowledge to start creating our own programs. The book will let you create programs such as a small Pokémon game, where Pokémon will be able to battle each other.

We will also be creating an app to deliver pizzas in outer space and the aforementioned Movie Night app to keep a list of your favorite movies. After creating our programs, you will be able to install the applications on an iPhone and show it to your friends. After being introduced to Swift and the knowledge and tools required to create an application for the iPhone, you should be able to continue to explore this area of programming. You should not only be able to continue working on the applications we create throughout this book, but also be capable of continuing the learning journey using other books or Internet resources. By using the skills provided in this book along with some imagination, a lot of fun and useful applications can be created for iOS devices such as the iPhone.
