I remember you had some feels about VIPER. Are those written up anywhere?

Wish it were more. asked me to write us an "architectural style guide" but I still don't know what I really want.

After finally understanding VIPER, I’m content with MVVM’s simplicity. It’s also well-suited to a stateless core.

Yes, for sure, but it fails to answer: how should we structure the stateful shell?

What’s the specific question?

User presses the "sign up" button. Who controls the state machine related to the resulting effects?

Original view model yields the new view model, original VC notices that and pushes on the corresponding new VC.

I don't mean UI-wise; in response to "sign up," you make some network request; when you get an ACK, persist a value, etc.
Replying to
The view model is responsible for coordinating that request-response chain. The details of it should live in the model.

What if the state machine related to that network request has a different lifespan than the UI related to it?
