Enjoyed this piece. You could argue that a few of the new features in Swift do offer more concise syntax e.g. inferred types and the ability to use map/filter – leading to reduced lines of code similar to ARC (but not quite as transformative as reducing state and memory bugs).

Nevertheless I would be interested in creating a framework to tackle the model/persistence/networking/reactive boilerplate issue. I imagine it would be very popular.

Also is there a Swift version of ReactiveCocoa?
