Kotlin Multiplatform (KMP)

Kotlin Multiplatform (KMP) allows you to share code between Android, iOS, Web, and Desktop. It emphasizes sharing logic (Business, Data, Networking) while allowing for native or shared (Compose Multiplatform) UIs.

When to Use

• Cross-Platform Shared Logic: Sharing core business logic, data models, networking, and validation across Android and iOS apps.
• Native UI Independence: Retaining 100% native UI performance (SwiftUI on iOS, Jetpack Compose on Android) while sharing domain code.
• Compose Multiplatform: Building shared user interfaces across Android, iOS, Desktop (JVM), and Web using Kotlin Compose.
• SDK & Library Development: Authoring multiplatform mobile libraries published to Maven Central and CocoaPods/Swift Package Manager.
