I know Chris lather's intention. And I have read and listen to all the interview he did. I think the question should be, Why was it necessary for Apple to bet on Swift. Something I dont think Bertrand Serlet or Avie Tevanian would have done.

That is the answer right there, they weren't the ones calling the shots and the direction bought into Chris' intentions.

Oh well. I guess this is another thing I could blame it on Craig Federighi.
