" summary

Argues that a single, testable core can run on Android and iOS by combining Kotlin Multiplatform with a pure Model View Update (MVU) core implemented as the Ulong library; effects live at guarded ports and messages are exhaustive via sealed classes. Shows a dice-rolling app with persistent roll history, Android using Litho and an iOS SwiftUI port that’s “not quite as good,” demonstrates declarative rendering, runtime-driven state fold, and notes Kotlin Multiplatform is promising but still rough around the edges.
