Welcome to Chapter 7. You are almost finished with the first section of this book. Only two chapters remaining! This chapter is going to be a bit different than our previous chapters. So far, we have been able to write code in our playground and that’s been it, but in this chapter, we are going to be working, partially, in Interface Builder! Don’t worry, we will not be starting a new Xcode project and fragmenting our references. We are going to keep our storyboard file in our playground, but more on that later.
