I am a visual person; I prefer to start with the visuals and make sure that the app looks like the design. Starting with the UI helps me to identify the data structure and allows me to get familiar with the app, which means I can then focus my attention on the code.

In earlier chapters, we set up our app structure and developed a good understanding of the basics involved. In this chapter, you will learn about app architecture and how to create it for our Let's Eat app. For this chapter, please use the Chapter 11 project files, as I have added more design elements that you will need throughout the book.

We will cover the following in this chapter:

• Understanding the Model View Controller architecture
• Classes and structures
• Controllers and classes
