This is a Kotlin Multiplatform project targeting Android (Jetpack Compose), iOS (SwiftUI), and Web (React).
-
/iosApp contains iOS applications. Even if you’re sharing your UI with Compose Multiplatform, you need this entry point for your iOS app. This is also where you should add SwiftUI code for your project.
-
/sharedLogic is for the code that will be shared between app targets in the project. The most important subfolder is commonMain. If preferred, you can add code to the platform-specific folders here too.
-
/sharedUI is for code that will be shared across your Compose Multiplatform applications. It contains several subfolders:
- commonMain is for code that’s common for all targets.
- Other folders are for Kotlin code that will be compiled for only the platform indicated in the folder name. For example, if you want to use Apple’s CoreCrypto for the iOS part of your Kotlin app, the iosMain folder would be the right place for such calls. Similarly, if you want to edit the Desktop (JVM) specific part, the jvmMain folder is the appropriate location.
-
/webApp contains web React application. It uses the Kotlin/JS library produced by the sharedLogic module.
To build and run the development version of the Android app, use the run configuration from the run widget in your IDE’s toolbar or build it directly from the terminal:
- on macOS/Linux
./gradlew :androidApp:assembleDebug
- on Windows
.\gradlew.bat :androidApp:assembleDebug
To build and run the development version of the web app, use the run configuration (webApp) from the run widget
in your IDE’s toolbar or run it directly from the terminal:
- Install Node.js (which includes
npm) - Build Kotlin/JS shared code:
- on macOS/Linux
./gradlew :sharedLogic:jsBrowserDevelopmentLibraryDistribution
- on Windows
.\gradlew.bat :sharedLogic:jsBrowserDevelopmentLibraryDistribution
- Build and run the web application
npm install npm run start
To build and run the development version of the iOS app, use the run configuration from the run widget in your IDE’s toolbar or open the /iosApp directory in Xcode and run it from there.
