We are about halfway through the setup of our UI structure. In this chapter, we created our Collection View with a dummy cell. Dummy cells allow us to continue to work on the basic structure of our app and focus on the design of the app, getting all of the assets ready to go before we add code. We also added our first prototype header, as well as presenting a modal to the user.

In the next chapter, we will complete the rest of our basic structure, before concentrating on adapting our structure to match our design.
