Ask HN: Is Swift production-ready?

I'm curious to hear which companies/developers out there are already using Swift in their production apps. I'm also seeking general opinions on how production-ready the language/toolbelt is, coming out of 1.0.

For me, it still feels very early to use Swift for a large-scale app. I've found in my own usage that many of the niceties of the language are offset by painful workarounds to make Objective-C APIs play ball. E.g. computing a random CGFloat within a CGFloat range

On the other hand, it seems obvious that Swift is the future of Cocoa development. And I'm reasonably confident that many of the current issues will be addressed within the next year.
