How to run the project? ✅
To run this project, you need the following:
- A machine running a recent version of macOS
- Android Studio
- The Kotlin Multiplatform Mobile plugin
- The CocoaPods dependency manager
Check your environment
Before you start, use the KDoctor tool to ensure that your development environment is configured correctly:
- Install KDoctor with Homebrew:
brew install kdoctor
- Run KDoctor in your terminal:
kdoctorIf everything is set up correctly, you’ll see valid output:
Environment diagnose (to see all details, use -v option): [✓] Operation System [✓] Java [✓] Android Studio [✓] Xcode [✓] Cocoapods Conclusion: ✓ Your system is ready for Kotlin Multiplatform Mobile development!
Otherwise, KDoctor will highlight which parts of your setup still need to be configured and will suggest a way to fix them.
Understanding the project structure
Open the project in Android Studio and switch the view from Android to Project to see all the files and targets belonging to the project:
Your Compose Multiplatform project includes 3 modules:
This is a Kotlin module that contains the logic common for both Android and iOS applications, that is, the code you share between platforms.
shared module is also where you’ll 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 module builds into an Android library and an iOS framework.
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.
This is an Xcode project that builds into an iOS application. It depends on and uses the
shared module as a CocoaPods dependency.
Run your application
To run your application on an Android emulator:
- Ensure you have an Android virtual device available. Otherwise, create one.
- In the list of run configurations, select
- Choose your virtual device and click Run:
Alternatively, use Gradle
Running on a simulator
To run your application on an iOS simulator in Android Studio, modify the
iosApp run configuration:
- In the list of run configurations, select Edit Configurations:
- Navigate to iOS Application | iosApp.
- In the Execution target list, select your target device. Click OK.
iosApprun configuration is now available. Click Run next to your virtual device.
Running on a real device
You can run your Compose Multiplatform application on a real iOS device for free. To do so, you’ll need the following:
TEAM_IDassociated with your Apple ID
- The iOS device registered in Xcode
Note Before you continue, we suggest creating a simple “Hello, world!” project in Xcode to ensure you can successfully run apps on your device. You can follow the instructions below or watch this Stanford CS193P lecture recording.
