Working on a small prototype debugger for TEA on iOS. On the left are the messages/actions, in the middle the state after that message, and on the right the full payload of the message. Works over Bonjour. Allows you to travel back in time as well.

The Elm architecture removes almost all responsibilities from the view-layer. However, you don't have to throw away UIKit, you can also remove a lot of responsibilities from UIViews and move them into your own code.
I haven't thought it through, but we could write a variant of drawRect which you can't override, but instead it takes a list of drawing commands (represented as an enum). Even better would be a type-system that guarantees only drawing effects, but I don't know if that fits Swift.
There are many implementations of that (VIPER, Clean Swift, etc.). In my opinion, they mostly add a lot of complexity. Some of the ideas in SOLID aren't bad, but all implementations I've seen are way too complex. I think something like the Elm architecture is more promising.
