Lesson 7 - When a single screen isn't enough - Navigation in iOS
In the previous lesson, Don't reinvent the wheel, use CocoaPods, we learned to work with CocoaPods, the package manager making the development for iOS devices easier.
In the apps we've created so far, one screen was enough. However, real applications probably couldn't do without multiple screens. That's why we're going to have a look at how to create multiple pages (controllers), how to navigate to them and how to return back.
Navigation Controller
For the navigation to work, we first need a Navigation Controller and then we
define individual Segues for the navigation. Let's get started
right away, we'll show everything on examples, including passing data to other
controllers.
Navigation Controller is responsible for navigating between assigned View Controllers. It automatically animates the transitions between them and provides us with a button to return back. We use it when we navigate between View Controllers that are ordered in a logical hierarchy and it makes sense for one to logically follows another (e.g. Registration -> Login or a hierarchy such as Settings -> General -> Software Update).

Now select the whole View Controller and assign the mentioned Navigation Controller to it. You can do so in the menu
