Project Structure

• /app-shared is the shared module that integrates all features.

  • commonMain is for code that's common for all targets.
  • Platform-specific folders contain platform-specific implementations.

• /core contains shared modules used across the entire project.

• /domain contains business logic and repository interfaces.

• /data contains data sources and repository implementations.

• /feature contains feature modules with UI and ViewModels.

• /app-ios contains iOS application entry point.

Build and Run Android Application

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 :app-android:assembleDebug

• on Windows

  .\gradlew.bat :app-android:assembleDebug

Build and Run iOS Application

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 /app-ios directory in Xcode and run it from there.
