Overview of Kotlin Multiplatform
Kotlin Multiplatform, part of the Kotlin ecosystem developed by JetBrains, has been gaining momentum since its introduction in 2017. It extends the capabilities of Kotlin to enable sharing of code across multiple platforms, including iOS, Android, Web, and Desktop. The main appeal of Kotlin Multiplatform lies in its ability to share business logic across platforms while allowing developers to build native UIs.
Key Features and Strengths of Kotlin Multiplatform:
- Code Sharing: The most significant advantage is the ability to share common code (like network calls, database access, and business logic) across platforms while keeping the UI layer native.
- Native Performance: As Kotlin does not impose a UI framework, applications can leverage native tools and libraries to ensure optimal performance.
- Interoperability: Kotlin is highly interoperable with existing Java code on Android and Objective-C/Swift code on iOS, making it a seamless addition to existing projects.
- Modern Language Features: Kotlin, as a language, offers modern language features like null safety, extension functions, and coroutines, which enhance the development experience and efficiency.
Kotlin in Multiplatform Development:
Kotlin’s role in Multiplatform development is central. It is a statically typed language known for its succinctness and expressive syntax, making the code more readable and maintainable. Kotlin’s support for coroutines provides a powerful tool for handling asynchronous tasks, a common requirement in modern apps. Kotlin’s ability to compile down to JavaScript and native binaries (via Kotlin/Native) is what powers its cross-platform capabilities, allowing developers to write platform-agnostic logic in a language they are familiar with.
Maintenance and Scalability
- Maintenance: Maintenance can be more challenging with Kotlin due to the need to manage both shared and platform-specific code. This dual management approach can sometimes lead to inconsistencies and the need for more thorough testing across platforms. Additionally, developers have reported occasional issues with project builds, which can be complex and tricky to resolve.
- Scalability: While Kotlin Multiplatform is scalable in terms of business logic, its scalability can be constrained by the complexities of managing multiple platform-specific UIs. This requires careful planning and architecture to ensure smooth scalability as the application grows.
Cost and Resource Implications
- Development Cost: Initial development costs with Kotlin Multiplatform can be higher due to the need for platform-specific UI development. However, shared business logic reduces time and resources in the long run.
- Resource Implications: Kotlin is well-established in the Android community, reducing training needs for Android developers. However, mastering Kotlin might require additional training, especially for developers unfamiliar with cross-platform development.
Future Prospects and Updates
- Recent Updates: JetBrains recently introduced Compose Multiplatform, a significant enhancement to Kotlin Multiplatform. This declarative UI framework allows developers to share UIs across platforms, including Android, iOS, desktop, and web. This addition is a notable advancement in Kotlin Multiplatform’s UI capabilities.
- Future Roadmap: With Compose Multiplatform, Kotlin Multiplatform is set to become more robust in cross-platform UI development. JetBrains is also developing Fleet, a new IDE expected to enhance the Kotlin Multiplatform development experience.
- Influential Trends: The integration of Compose Multiplatform and the development of Fleet could make Kotlin Multiplatform a more appealing choice for developers seeking a Kotlin-centric cross-platform solution, potentially increasing its future adoption.

Both Flutter and Kotlin have their unique growth paths and challenges. Flutter’s all-in-one approach contrasts with Kotlin Multiplatform’s blend of shared logic and native UIs. The introduction of Compose Multiplatform and Fleet by JetBrains signifies a substantial step towards a more integrated and efficient development experience in Kotlin Multiplatform, potentially influencing its adoption and popularity in the future.
