Demo of using ReactiveCocoa with Swift at MBLTDev 2014. Slides are available online.
You'll need to clone this repo, not download it's zip file.
git clone https://github.com/AshFurrow/MBLTDev.git
cd MBLTDev
git submodule update --init
./submodules/ReactiveCocoa/script/bootstrapAnd open the main Xcode workspace.
So basically this is a bare-bones setup for what an app using Swift with ReactiveCocoa would look like. Create a workspace with your app and add ReactiveCocoa and LlamaKit. You also have to have your app's target build against ReactiveCocoa and LlamaKit in order to work (at the moment).
