This is the last section in the chapter (page 281).
Once it got time to get practical, I’m thoroughly confused.
1 - recursiveDescription generates a warning for an undeclared selector.
2 - How do i control what I’m building, Debug or release?
3 - I built for analysis and now I’m getting a no implementation error for TouchTrackerTest. I get why, but I don’t get know how to get rid of it.
This seems like a huge deal, specifying build settings and this is a page and a half. Is there a better resource for understanding this stuff out there?
