The goal of this book is to teach you iOS development using Swift in a manageable way without overwhelming you. We focus only on the essentials and cover the material in a hands-on practice manner for you to code along. For beginners, the book starts with an introduction to the Swift programming language, and how to accomplish common programming tasks with it. You will then start building the user interface of a complete real-world application, using the latest version of Xcode, and implement the code for views, view controllers, data managers and other nitty-gritty of a mobile application. By the end of this book, you will know how to write and publish apps, and more importantly, how to use what you have learned to build your own apps.
