This is certainly pragmatic, effective advice.

However…if you care as much about dependency management as I do (and chances are you don’t), and don’t have a direct dependency on CoreGraphics in that code (and chances are you do), then this is slightly stomach-churning, in addition to pragmatic and effective.
Pulling in a dependency on CoreGraphics just to get those types is awful, in addition it makes it harder to make code that works on both Mac OS X and iOS. After going back and forth on this for quite some time, I decided to standardize on the Foundation types and have a tiny compatibility layer, which you can find on github: https://github.com/mpw/MPWFoundation/blob/master/Classes/PhoneGeometry.h
