Apple Watch / Watch OS 2 Native Plugin, any success?

Has anyone successfully got Unity talking to an Apple Watch running Watch OS 2? There are some examples out there of plugins working with Watch OS 1, but I can’t find any examples using the new WatchConnectivity / WCSession class. Would greatly appreciate any pointers, as I have yet to manage to get my own plugin working.

Too soon for watchOS 2, it just got pulled and will be delayed for unforseen bugs.
