I'm currently reading Ian O'Connor's book on Sebastian Telfair, "The Jump."
Ainge pops up in the book a couple times. Swift was part of the same high-school-to-pros cohort that Telfair headlined (along with Dwight Howard, Shaun Livington, Al Jefferson, Josh Smith, J.R. Smith, and others) in the 2004 NBA draft.
What's funny is despite rumors of this infatuation with Swift, Ainge is quoted in the book on a couple occasions as being pretty critical of Swift's talent level. (He does rave about Telfair.)
Perhaps it's another example of Ainge's gamesmanship, saying one thing and meaning another. At face value, though, those comments make me think that Ainge's man-crush (bro-mance?) on Swift is totally exaggerated.
That said, I'd be surprised if Swift isn't invited to summer camp this coming offseason.
