This change was around June 2014, it is included in Xcode 6 which was released around September 2014. The API won't exist in Xcode 5 installations, but I don't think that's a large number of users.
Yeah we need to figure out how to regenerate the on-line API documentation, I don't know exactly how Dan generated it. It's about a year and a half old at this point.
