If I were writing a new app, today, I wouldn’t use it. If was considering adding support for Rx in an existing app, I’d probably wait.

And I know of at least one project where RxSwift support is being pulled.

In our shop, we officially support the current version minus one. In September, that will be 13 and 12. Next September, that’s 14 and 13 and we’re off to the races.
