Grocery List App Interface Builder
You made it! Welcome to the second part of the book. Chapters 9–12 are going to walk you through building a Grocery List app. It might not sound very exciting, but it will be. We are going to use the knowledge we gained throughout the first section about API design, design patterns, protocol-oriented programming, and testing to build a clean and concise app. This chapter, along with Chapters 10–12, will cover the design for the app or MVP (minimal viable product).
