Compiler problem

on step three when it came time to print quote with an item from the array it makes me use "[self.quotes objectAtIndex:2]" and when i didn't specify self it said error. Since the array is being initialized inside the scope of viewDidLoad shouldn't just saying [quotes objectAtIndex:2] be fine?

self.quotes is actually calling an accessor for the internal _quotes backing variable.

In your viewDidLoad method you would actually have to call: [_quotes objectAtIndex:2] to get direct access to that "inner variable" backing the quotes property.
