In this chapter, we learned how to install the Xcode app and how to use it in general. We are familiar with the basic components of the IDE and we have created our first playground. It was pretty basic, but we know how to write Swift code, which is automatically evaluated. We can read the errors and we can try to resolve them.
The next chapter will teach us how to create our first mobile app. It will explain the structure of a mobile project and how to start adding simple features to it. Let's dive deep into iOS and produce something which can be executed on mobile devices.

Overview of this book
Swift Language is now more powerful than ever; it has introduced new ways to solve old problems and has gone on to become one of the fastest growing popular languages. It is now a de-facto choice for iOS developers and it powers most of the newly released and popular apps. This practical guide will help you to begin your journey with Swift programming through learning how to build iOS apps.
You will learn all about basic variables, if clauses, functions, loops, and other core concepts; then structures, classes, and inheritance will be discussed. Next, you’ll dive into developing a weather app that consumes data from the internet and presents information to the user. The final project is more complex, involving creating an Instagram like app that integrates different external libraries. The app also uses CocoaPods as its package dependency manager, to give you a cutting-edge tool to add to your skillset. By the end of the book, you will have learned how to model real-world apps in Swift.
