Companies are increasingly adopting Kotlin Multiplatform (KMP) to reduce code duplication and maintenance costs in existing mobile applications. According to Alexey Artamonov of Nord Clan, the decision to migrate should be based on a cost-benefit analysis over a three-to-five-year horizon.
A full migration is often unnecessary. Instead, companies can implement KMP selectively by moving specific modules, such as business logic, data processing, networking, authorization, and corporate service integrations, into shared code.
The KMP ecosystem currently lacks the volume of libraries available for native Android or iOS development. Developers often face challenges when integrating Swift-only libraries, as Kotlin/Native does not support direct imports of Swift modules without Objective-C interfaces.
Effective KMP architecture relies on identifying which components depend on platform-specific features. Logic related to UI, camera, geolocation, or system services should remain native, while platform-agnostic business rules are the best candidates for shared modules.
