Overview

The kmp-viewmodel is a Kotlin Multiplatform library that provides shared MVVM for UI applications. It supports Android Parcelable, Kotlin Parcelize, and AndroidX SavedStateHandle for state restoration after process death. It also offers easy interoperability with Swift/Objective-C and SwiftUI, and supports Compose Multiplatform Framework for various platforms. The ViewModel class serves as a business logic or screen level state holder, exposing state to the UI and encapsulating related business logic. Its main advantage is that it caches state and persists it through configuration changes on Android. The library is available on Maven Central and is licensed under MIT.
