Rather than abstracting away platform differences, KMP embraces native development by sharing only the code that benefits from sharing — business logic, networking, repositories, and domain models — while leaving UI and platform-specific layers fully native. It achieves this through three compilers: Kotlin/JVM for Android, Kotlin/Native for iOS and other targets, and Kotlin/JS for web. Android interoperability is nearly seamless since Kotlin is already native to the ecosystem, while iOS requires a translation layer through Kotlin/Native to generate Objective-C interfaces consumable by Swift. This introduces interoperability costs around collections, coroutines, Flow, exceptions, generics, and memory management — though tooling like SKIE and KMP-NativeCoroutines has significantly reduced these pain points. The core KMP philosophy is 'share what makes sense, keep everything else native,' not 'write once, run anywhere.' ## Full article daily.dev links to this article rather than hosting it.
