Hi Colin,

This is one of *many* things that we are interested in working on some day, but we need to stay focused on shorter term goals (like getting to ABI stability) to make sure we are successful with those.  If you’re working on Apple platforms, Swift does interoperate with the Objective-C KVO implementation, using the “dynamic" keyword.
