What's the reason for the "resource value" API on NSURL not being present in
SwiftFoundation?

Is there interest in bridging between dispatch_data_t and NSData similar to
what's available with Darwin Foundation. Being able to avoid buffer copies
seems like a big win. And with libdispatch (almost) being available on Linux,
would it make sense to back (immutable) NSData with libdispatch in
You can't have AutoreleasingUnsafeMutablePointer without Objective-C
interop.

Well, there's
func resourceValuesForKeys(_ keys: [String]) throws -> [String : AnyObject]
which doesn't use AutoreleasingUnsafeMutablePointer, but that doesn't exist in
Swift, either.
And the other one could have a replacement like so:
func resourceValue(forKey key: String) -> AnyObject throws
The semantics of the methods are fairly nuanced in ObjC.
You can have a resource value that fails to be fetched, or one that
succeeded to fetch but had no value. A Swift version would model this as
`throws -> AnyObject?`.
For the dictionary version, you may ask for a resource value, it
succeeds,
