I think the point is that, perhaps, ios and osx developers' biggest pain point was not objective c, but rather the regressions and missing features of the development environment. Taking on a whole new closed source (at least for now) language seems like it spreads resources a little thin -- even at Apple.
Since it's already done I don't want swift to go away at this point. However, if given a choice between keeping objc and having a much better development environment or getting a totally new language (and the division it will bring) and a buggy IDE, I would've picked the former.
