Visited the NSValue class, dictionary objects, enumerating the dictionary and Set objects. Just when I think I have learned all of the structures available, here come Sets and its associated methods. Does it ever end? How do they expect a developer to remember all of these things and when to use them?
Well, anyway. Tomorrow I finish reading this strange chapter and start attempting the 11 exercises (not a typo). This should be interesting and could take a week to complete ;)
