What does that mean?  If you want a CGSize, does that mean you have to
use "sizeValue" on what is returned and convert it?

Yes; what is returned is an object (NSValue) containing the size. You call -sizeValue to get the size itself. KVC always returns an object as a value, so if it's a scalar type, you have to "unwrap" it.
