I'm looking for some samples of ReactiveUI running in Xamarin.iOS. I checked out the iOSPlayground project, but it doesn't compile using the latest Xamarin.iOS alpha builds. Once I worked past the compilation error, I got a cryptic exception thrown from within monotouch when running in the iOS simulator. I know the iOSPlayground isn't meant to be an actual sample implementation.

Is there a proper sample implementation for MonoTouch/Xamarin.iOS? I'd be fine with ReactiveUI 4.5, if that's all that is available.
