What are breakpoints used for?

I just watched the video on breakpoints and debugging. At the end Amit talks about how you can set breakpoints on specific lines of code. Is that so that you can isolate where things might be broken? I'm a little confused as to use cases when I'd want to just run bits of my code at a time.

Breakpoints stop execution at a particular area in your code. For example, say you have a 300 line project. You notice your output isn't what you expected. You could set a breakpoint at every 25th line following each run, and try to spot where the error occurs. They're just a way of keeping you from pulling your hair out, or swearing at your computer... Maybe.

Here's a good blog post on breakpoints: http://jeffreysambells.com/2014/01/14/using-breakpoints-in-xcode
