Is the medium/long term view? ie, that the Swift implementation will be
"SwiftFoundation", with function renaming done to drop the "NS",
thereby allowing developers to keep their existing applications on the
Obj-C implementation, or consciously decide to migrate to the Swift version?

that with Swift 3, the foundation classes will be rewritten in swift. So
does this mean that all Swift classes using Foundation automatically start
using Foundation written in Swift or is it opt-in? If it’s mandatory,
then will libraries dependent on the Objective-C runtime no longer work
(i.e. the Alamofire git repo)?<br class="">
<br class="">
The foundation classes are not being re-written in Swift (for Darwin, the
linux versions however are). The current proposal on the evolution list
is for structures, which act in parallel to their reference type counterparts.
You can still use a reference type where it makes sense, but now you can
use a struct type where that is desired for a few new types.<br class="">
<br class="">
One slight change that might have some effect is how the APIs are imported.
If an API exposed a return type of NSData now it will return a struct Data.
That can easily be converted back via using `as NSData`.<br class="">
