No, he means Swift and Objective-C. That's what was, is and will be supported.
On the other hand, Microsoft's API screw-ups are legendary at this point... not even they know what developers should use for Windows apps. I think Windows Phone was recently canceled, so that simplifies things a bit.
And even if there was such a blessed SDK/language combination, they'd probably drop it or rename it next year ;-)
I can also pick up Objective-C class specific methods and classes that were dropped.
