An example of Kotlin Multiplatform todo app with shared Android/Desktop Compose UI and SwiftUI (not Compose) iOS. This example supports the following targets: - `Android` (Compose) - `Desktop/JVM` (Compose) - `Web/JavaScript` (Compose) - `iOS` (SwiftUI, not Compose) Libraries used: - Jetpack Compose - shared UI - [Decompose](https://github.com/arkivanov/Decompose) - navigation and lifecycle - [MVIKotlin](https://github.com/arkivanov/MVIKotlin) - presentation and business logic - [Reaktive](https://github.com/badoo/Reaktive) - background processing and data transformation - [SQLDelight](https://github.com/cashapp/sqldelight) - data storage There are multiple modules: - `:common:utils` - just some useful helpers - `:common:database` - SQLDelight database definition - `:common:main` - displays a list of todo items and a text field - `:common:edit` - accepts an item id and allows editing - `:common:root` - navigates between `main` and `edit` screens - `:common:compose-ui` - Shared Compose UI for Android and Desktop - `:android` - Android application - `:desktop` - Desktop application - `:web` - Web browser application + Compose Web UI - `ios` - iOS Xcode project The root module is integrated into Android, Desktop and iOS (non-Compose) apps. Features: - 99% of the code is shared: data, business logic, presentation, navigation and UI - View state is preserved when navigating between screens, Android configuration change, etc. - Model-View-Intent (aka MVI) architectural pattern - Pluggable UI - Compose UI for Android, Desktop and Web, SwiftUI (not Compose) for iOS ### Running desktop application * To run, launch command: `./gradlew :desktop:run` * Or choose **desktop** configuration in IDE and run it. ![desktop-run-configuration.png](screenshots/desktop-run-configuration.png) #### Building native desktop distribution ``` ./gradlew :desktop:package # outputs are written to desktop/build/compose/binaries ``` ### Running Android application Open project in Intellij IDEA or Android Studio and run "android" configuration. ### Running Web browser application * To run, launch command: `./gradlew :web:jsBrowserDevelopmentRun` * Or choose **browser** configuration in IDE and run it. ![browser-run-configuration.png](screenshots/browser-run-configuration.png) ### Running iOS application Open and build the Xcode project located in `ios` folder. ![Desktop](screenshots/todo.png)
