Kotlin Multiplatform - True power of native code reuse

Their first attempt at sharing 25% of their code failed spectacularly. Their second attempt, sharing 80%, succeeded. Discover the counterintuitive key to adopting Kotlin Multiplatform.

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.

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.

Key takeaways for starting with Kotlin Multiplatform

Developers should deeply understand Kotlin Native's strict memory model, be aware of coroutine limitations, and build a thorough proof of concept before starting a project.

Future plans for the open source architecture

The team plans to integrate a dependency injection framework like Koin, improve thread-bound object scoping, and release the architecture as an open source project.
