[swift-corelibs-dev] Making Foundation classes easier for Swift development

Hi Ryan,

I don’t have anything concrete yet, but we are taking a very close look at the effect of dropping NS on items in the global namespace. I think it’s pretty clear we will need to do something to make the scope of those constants clearer once the prefix is gone.

What I have been working with most recently has been NSFileManager and its `attributesOfItemAtPath` method which returns a type of [String: AnyObject]. Due to the nature of this, I’ve had to do some digging into the existing corelib-foundation source of NSFileManager to see how each item is assigned and which ones are guaranteed to be set and which ones I should be cautious of (e.g. could be nil).

For the time being I have written my own small Swift module <https://github.com/RyanBreaker/SwiftFileAttributes> for handling this easier, but I can’t help but feel edgy about it with all the explicit optional unwrapping.
