And that the Obj-C versions of the prototypes are in the guide, which hasn’t
been updated for Swift.

Actually, that’s what happened, but only as I was typing in my first guess. It
was the same except I mapped, based on the Swift w/ Cocoa & Obj-C guide, the
“id *” in the KVC guide to a “UnsafeMutablePointer<AnyObject>”. Anyone know
