That turned out not to be quite as true as they said it was...

> While the WWDC app does in fact use Swift, it’s not as much as you might think. Out of 281 classes, only 6 are written in Swift. The Apple Store app is also using Swift for its watch app. That’s about all the production Swift I could find from Apple on iOS.

They are using on more on the Mac. Parts of Mac OS X El Capitan are written in Swift.
Federighi said on Gruber's podcast that the Dock team completely rewrote Dock in Swift. However most of the other OS X teams are only testing the waters. A big part of it is lack of 32-bit support for Swift apps.
Federighi said:

" the team that does the Dock and the window management on OS X, implemented all their new features for El Capitan in Swift and started mass-converting all of their code, and say that they couldn’t imagine going back and that they’re more productive with it."

So the window management team is also using it.

Only the dock IIRC.
