You must have thought that developing with Swift makes creating an app straightforward, right? Unfortunately, it does not. This long chapter showed that most of the coding is devoted to configuring components of the SDK and creating connections between the classes of our app, instead of using cool functional programming tricks.

However, in this chapter, we covered most of the aspects that an iOS developer must know, starting with CocoaPods, to laying out the components of the views and differentiating responsibilities between the different layers of an app.

Another important skill you need to learn is how to connect to a server to retrieve data—a server that could be either under our control, or a third-party server, such as a service.

In the next chapter, you'll learn how to exploit external servers to add content to an app, and retrieving and sending JSON data. We'll pack this technique to create a pretty weather app.
