An initial architecture for sharing pure functions

The first attempt involved a reactive clean architecture that shared only 25% of the code as pure functions to minimize risk.

Discovering critical challenges in Kotlin Native

Key implementation blockers included the strict memory management model, threading issues with coroutines on iOS, and limitations with generics.

#5about 5 minutes

A revised architecture sharing everything but the UI

The successful solution involved sharing 80% of the code, including the entire business logic and presentation layers, to minimize jumps between native and shared code.
