Kotlin Multiplatform
Kotlin Multiplatform is a technology developed by JetBrains that enables developers to share code across multiple platforms, including Android, iOS, web, desktop, and server-side applications, using the Kotlin programming language. It allows writing common business logic, data models, and utilities once in Kotlin and compiling them to native binaries or JavaScript for different targets, reducing duplication and improving consistency. This approach facilitates cross-platform development while maintaining access to platform-specific APIs and performance optimizations.
Developers should learn Kotlin Multiplatform when building applications that need to run on multiple platforms (e.g., mobile apps for both Android and iOS, or web and desktop versions) to maximize code reuse, reduce development time, and ensure consistent behavior across platforms. It is particularly useful for teams already using Kotlin for Android development who want to expand to iOS without learning Swift or Objective-C, or for projects requiring shared logic in backend and frontend systems. Use cases include cross-platform mobile apps, games, and enterprise applications where maintaining separate codebases is costly or error-prone.
