FR: Offline Documentation

Right now, I am writing an app in Swift with Firebase and am finding the documentation hard to work with. First off, all of the documentation is for Objective C so I always need to try to translate it upon reading to its Swift equivalent:

Because this is really hard to use, I frequently make use of the [iOS - Swift online documentation](https://firebase.google.com/docs/reference/swift/firebasecore/api/reference/Classes). Since I often work offline though, I am usually stuck with the not-very-helpful Objective C quick help documentation. For certain libraries with similar problems, I use their supported documentation on [Dash](https://kapeli.com/dash) for offline usage.

I would like to propose the creation of a [Dash docset](https://kapeli.com/docsets) for Firebase so people can view the documentation offline. While I primarily care about Swift since it is the language I am writing in, Firebase could potentially provide all documentation of its documentation for all of its supported platforms through Dash.

Also, on a side note, while I am not sure if it is even possible, it would be great to have native Swift documentation for Firebase. I rely on the quick help documentation often and having it readable to Swift developers would be a big bonus.
