Issue Description:

I'd expect this to return a enumerator over URL, but instead it's an enumerator over Any:

Consider the following Swift:

import Foundation

let enumerator = FileManager.default.enumerator(at: URL(fileURLWithPath: NSTemporaryDirectory()), includingPropertiesForKeys: nil)!
for url in enumerator {
    print("\(url.path)")
}

This results in the following compiler error:

enumerator.swift:5:14: error: value of type 'Any' has no member 'path'
    print("\(url.path)")
             ^~~ ~~~~
enumerator.swift:5:14: note: cast 'Any' to 'AnyObject' or use 'as!' to force downcast to a more specific type to access members
    print("\(url.path)")
             ^
             (   as AnyObject)

It'd be nice if there were a Swift overlay/shim that could improve this here. The situation today is that you have to have to force cast to `URL`.

We can't break source compatibility, but I'm keeping this issue to see if we can make use of this feedback.
