First, I spent all day looking at old/outdated tutorials online before I came across multiple recommendations for this book. I was ecstatic to find out it was just released a month ago and is using the current version of Xcode. Perfect timing!
I just did the first chapter, and it worked wonderfully. However I ended up with the following code at the top of my QuizViewController.m file:
[code]@interface QuizViewController ()
Right before @implementation.
I don’t know how it got there, or what it might be for. (It doesn’t seem to do anything - I tried deleting it and everything still worked fine.)
