Frankly, it makes me feel bad for Chris Lattner. This guy's been worked his ass off to create a genuinely new language with all the bells and whistles he can fit, and his employer is the one that held him back the most. It took years for Foundation framework to get serious multiplatform commitment, and unless something changes drastically I think that's going to be the sour taste that developers have in their mouths.

Apple in general seems to only understand software development through the lens of oppressive control. Maybe that's a security imperative for consumer products, but in Open Source it is an outright suicide pact. You have to treat every major platform as a first-class target, otherwise the major platforms will all switch to something better.
