> I like things like the MVVM pattern, but it's been my experience that it's really not such a good idea to implement it in UIKit, because UIKit was designed explicitly for MVC. I have learned that those ugly-ass UIViewControllers are really important, and I circumvent them at my peril. I agree with everything you've said but this. I've worked on 3 very large app, one which is 85% using mvvm, the two others were still in experimentation phases with it and I am not sure where they've ended up. It's been a joy. The app is designed in a very reactive way and the data flow paths are very clearly defined and easy to follow. Don't get me wrong the other two apps were heavily MVC with a lot of delegation and that was fine. I could easily switch back to an architecture like that but it's very possible and quite easy to switch over to an mvvm pattern.
