Chapter 9
Understanding Struct, Project Organization and Code Documentation

Most good programmers do programming not because they expect to get paid or adulation by the public, but because it is fun to program.

- Linus Torvalds

If you read from the very beginning of the book and have worked through all the projects, you've gone pretty far. By now, you should be able to build a list-based iOS app using SwiftUI. We'll further enhance the FoodPin app and add more features. However, before diving deeper into iOS app development and learn other APIs, I want to introduce you the basics of Object Oriented Programming and teach you how to write better code.

Don't be scared by the term "Object Oriented Programming" or OOP in short. It's not a new kind of programming language, but a programming concept. While some programming books start out by introducing the OOP concept, I intentionally left it out when I began writing this book. I want to keep things interesting and show you how to create an app. I don't want to scare you away from building apps, just because of a technical term or concept. Having said that, I think it's time to discuss OOP. After going through 8 chapters and you're still reading the book, I believe you're determined to learn iOS programming. And, I believe you really want to take your programming skills to the next level to become a professional developer.

Okay, let's get started.
