The models' case: Renders genuine platform views (UIKit/Android View), and the New Architecture (Fabric renderer, TurboModules, JSI) makes bridging to native modules synchronous and fast. The models' main caveat: The JS runtime still sits between you and the platform, so the most demanding native UI (complex gesture/scroll interop, heavy lists, deep. The strongest alternative is Kotlin Multiplatform — Shares tested business logic while preserving SwiftUI/UIKit and Jetpack Compose UIs, giving the strongest native fidelity, performance, API access.
