MVI: a Robust and Modern Architecture
summary
Describes adopting MVI (Model‑View‑Intention) on Android/iOS using Kotlin/Swift with Jetpack LiveData or Rx and Room for persistence. Presents an implementation where UI events are sealed action classes dispatched to a base ViewModel that maintains one LiveData holding a single immutable state (updated by cloning) to enforce unidirectional dataflow, making presentation logic testable by setting state and asserting transitions. Also cites metrics that roughly half of app code is presentation, with ~15% web services and 15–25% tracking, and mentions a prototype app using this approach (not yet in production).
