10. Recent State of ReactiveCocoa
11. New Member • @RuiAAPeres Issues • Reduced from around 250 to 80+ (as of 2016-04-26)
13. Moving Rex to the ReactiveCocoa org #2790 1. Discoverability 2. Credibility 3. Expansion 4. Easier to manage
14. Split Objective-C and Swift APIs going forward #2807 Correct me 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?
