It’s frustrating. The debugger has to know the structure of every object and it apparently doesn’t. It used to be much worse, though. Like with NSArray’s, they’re an array of objects. The debugger doesn’t know what type of objects specifically, and that’s due to the Objective-C language, not the debugger.
As you dive into iOS development, I think you’re going to find that Apple is about 15 years behind its competitors when it comes to development. That’s no joke. But they’re catching up and, trust me, it used to be much worse!
