I’m really enjoying this book so far - great stuff! There was one thing that I messed up on which took me a little while to find that I think might be worth mentioning, however. I renamed something that was assigned as an outlet in Interface Builder (or maybe it was an action? It’s been a little while) and I was getting unexpected behavior. It took me quite a bit of digging to figure out what had happened - and I overlooked the little exclamation point in IB that indicated something was amiss at first.
You might cover this later in the book, but do you think you could include a paragraph or two about how to tell when something is wrong in IB? Since the project will still compile and run, apparently without warnings, I’ve found it somewhat hard to diagnose problems there. Any tips you might have would be appreciated - and I’m sure other people have done things like this. At least, I hope they have. ;)
