Summary
This chapter stepped you up to writing and running a program of your own. It introduced the first level of debugging: what to do when your program crashes. It turns out that Xcode offers good facilities to help you analyze a crash without you having to do much. You accepted Xcode’s guidance, quickly traced the problem, and verified that your fix worked.
But we’re not done with passer-rating. There are still bugs in it, and this time you’ll have to hunt for them.
