iOS devs can finally claim functionality that our Java counterparts have been taking for granted: "nullable" annotations in ObjC which transfer to Optional Swift types!

I hope we can start using these in our app ASAP. It will help ObjC dev efforts a ton while also easing our (not too distant) transition to Swift. I think that all we need to do is specify Xcode 6.3 as the minimum supported Xcode version. I'm guessing lesser versions will fail to compile the code if they encounter one of these new pragmas or annotations.
