It is definitely more strongly typed than objective c. Swift's type inferencing is up there with Haskell, and Objective C/XCode's 'find all uses' is still string based.

Totally agree with your 'reduce ambiguity' observation, and I think long term Swift will do very well there. It will also will allow tooling to radically improve from what it is, and multicore to have a reasonable chance to be helpful.

Imo it seems a lot of the language decisions they have made are to make it more compiler/memory friendly (eg the way assign works with arrays). That bodes well for speed/memory/battery I think.
