Project structure

This Compose Multiplatform project includes three modules:

shared

This is a Kotlin module that contains the logic common for both Android and iOS applications, the code you share between platforms. This shared module is also where you write your Compose Multiplatform code. In shared/src/commonMain/kotlin/App.kt, you can find the shared root @Composable function for your app. It uses Gradle as the build system. You can add dependencies and change settings in shared/build.gradle.kts. The shared module builds into an Android library and an iOS framework.

androidApp

This is a Kotlin module that builds into an Android application. It uses Gradle as the build system. The androidApp module depends on and uses the shared module as a regular Android library.

iosApp

This is an Xcode project that builds into an iOS application. It depends on and uses the shared module as a CocoaPods dependency.
