if I'm wrong, but maintaining both an Objective-C and Swift API for RAC is a bit of a burden, right? Perhaps going forward it's worth thinking about slimming ReactiveCocoa down to just support Swift. I'm sure you guys feel the pull of writing things in Swift as much as I do ! Obviously there's a lot of people reliant on the Objective-C APIs (myself included, for some rather large projects) but if there's support for this idea, splitting the language support up into separate repos/projects might be a good ﬁrst step? What do you think?
