KMP is not the final step to accomplishing 100% shared code across all platforms, but it is the natural next step towards that goal. KMP is a feature of Kotlin which shares code between an app’s various platforms, so that each platform’s natively programmed UI calls into the common code. Kotlin is a statically-typed programming language that bears a striking resemblance to Swift, and is 100% interoperable with Java. Think about your iOS current project: is it available on any other platforms, like Android or the web? If so: how much logic does your iOS app share with its counterparts on those other platforms? If not, but making your app available on another platform is on the roadmap, how much will developing on the next platform force you to repeat yourself? Either way, the answer is probably: a lot.Įnter Kotlin Multiplatform (KMP). And more shared code across platforms means less repetition, which means better code. Trying to minimize repetition is just good programming. It allows developers to share knowledge domains and reduce duplication of native code.DRY (or Don’t Repeat Yourself) is one of the foundational principles of programming, but repeating lots of logic has been often necessary to develop an app running on multiple platforms. Kotlin allows a high level of reusability between developers. KMM enforces modularization, forcing us to write our code in a way that shields business logic from UI. On the other hand in UI first approach, business logic and rules are tightly coupled into the UI layer.
KMM focuses on a logic first approach, our application’s business layer is cleanly separated from the UI layer. We can write as much common code as needed, and anywhere in the entire application, we can just write native code. Kotlin doesn’t lock us only to the framework supported features. This is where KMM is different from Flutter and React Native. This means that if our selected framework (Flutter or ReactNative) doesn’t have a particular capability, or it doesn’t support new features introduced recently by Android or iOS, we get blocked.
Whatever these frameworks (Flutter/ReactNative) support, we get tied to these restrictions. When we work with Flutter or React Native we lock our-self in their ecosystem. But in case we want to write platform-specific code in the business logic layer, KMM also provides us that flexibility. We have to write platform-specific code to implement only the UI.
With KMM we can have a single codebase for the business logic for both iOS and Android apps.
Android and iOS versions of any App have a lot of common functionality, but they can differ in terms of UI as the UI components provided by Android and iOS have their own look-n-feel. It uses the multiplatform capability of Kotlin. Kotlin Multiplatform Mobile is an SDK provided by JetBrains for cross-platform mobile development.
