Summary

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.
