Kotlin Multiplatform in production
By Rodrigo Sicarelli 1 min read
Kotlin Multiplatform is production-ready for sharing non-UI logic across iOS and Android. Share the layers that change most — networking, serialization, persistence, domain — and invest in build setup and toolchain pinning, which is where teams actually lose time.
Kotlin Multiplatform has moved well past the experiment phase. Sharing business logic across iOS and Android is no longer a bet — it’s a practical default for teams that want one source of truth for the parts of the app that aren’t the UI.
Where it pays off
The biggest wins come from sharing the layers that change the most and break the most: networking, serialization, persistence, and domain logic. Keeping those in one place means a bug is fixed once and a feature ships to both platforms at the same time.
What still needs care
Build setup, native interop, and dependency alignment are where teams lose time. Pinning the toolchain and treating the shared module like a real library — versioned, tested, documented — is what separates a smooth rollout from a painful one.
This is a sample post that exercises the blog template, tags and reading time. Real writing follows.
FAQ
- Is Kotlin Multiplatform ready for production?
- Yes — for sharing non-UI logic (networking, serialization, persistence, domain) across iOS and Android it is a practical default, used by many teams in shipping apps.
- What should you share with KMP, and what not?
- Share the layers that change and break the most — the business logic. Keep each platform’s UI native; KMP targets the shared core, not the presentation layer.
- Where do teams lose time with KMP?
- Build setup, native interop, and dependency alignment. Pin the toolchain and treat the shared module as a versioned, tested, documented library.
