The KMP internal war is a friction point many multi-platform teams face. Android engineers naturally push for shared logic via Kotlin Multiplatform, while iOS engineers frequently push back against introducing a heavy Kotlin/Native runtime dependency into their app.
To break this runtime deadlock, we can implement a Headless Mobile Architecture.
This strategy shifts the core data layer into a single, ultra-lean core module built in Rust. Using automated UniFFI bindings, it compiles directly into pure, native target languages:
🤖 Android: Clean, idiomatic Kotlin
🍏 iOS: Lightweight, pure Swift
🌐 Web: High-performance TypeScript/Wasm
This approach preserves total team sovereignty with zero UI compromises, zero cross-platform runtime bloat, and zero political friction. Swipe through the infographics below to see the architectural breakdown.
The complete engineering proposal, including build configurations and production implementation specs, is live on Level Up Coding.

A proposed 'Headless Mobile Architecture' uses Rust as a shared core data layer to sidestep the political and technical friction of Kotlin Multiplatform adoption on iOS. By compiling Rust via UniFFI bindings into native Kotlin, Swift, and TypeScript/Wasm targets, teams can share business logic without imposing a Kotlin/Native runtime on iOS engineers. The approach claims zero UI compromise, zero cross-platform runtime bloat, and no team sovereignty conflicts.
