Verified directly (java.util.Locale, NSLocale, and Intl.DisplayNames all tested outside the app) that every platform's locale data resolves "EU" correctly on its own — "European Union" in en, "Union européenne" in fr, "Europäische Union" in de, etc. — via CLDR, which defines "EU" as a grouping in its own right despite it not being a real ISO 3166-1 country code. The hardcoded English fallback was based on an assumption that was never actually verified. Removes the special case from the shared code entirely. That required two platform-side fixes to stop blocking "EU" from ever reaching the platform lookup: - JVM/Android: dropped the Locale.getISOCountries() membership guard (which excluded "EU") in favor of detecting an unresolvable code by getDisplayCountry() echoing it back unchanged. - Web: jsRegionDisplayName() was hardcoding locale 'en' for Intl.DisplayNames — changed to undefined (the browser's own locale), matching what the other platforms already did. Without this fix, "EU" would resolve, but only ever in English on web. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FXcrACM5sok3M1KQJ8kByy

Supported Platforms
iOS 16.0+ • macOS 13.0+ • Android 10.0+
Kotlin Multiplatform
This is a Kotlin Multiplatform project targeting Android, iOS, Web, Desktop (JVM).
-
/iosApp contains an iOS application. 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.
-
/shared 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.
Running the apps
Use the run configurations provided by the run widget in your IDE's toolbar. You can also use these commands and options:
- Android app:
./gradlew :androidApp:assembleDebug - Desktop app:
- Hot reload:
./gradlew :desktopApp:hotRun --auto - Standard run:
./gradlew :desktopApp:run
- Hot reload:
- Web app:
- Wasm target (faster, modern browsers):
./gradlew :webApp:wasmJsBrowserDevelopmentRun - JS target (slower, supports older browsers):
./gradlew :webApp:jsBrowserDevelopmentRun
- Wasm target (faster, modern browsers):
- iOS app: open the /iosApp directory in Xcode and run it from there.
Running tests
Use the run button in your IDE's editor gutter, or run tests using Gradle tasks:
- Android tests:
./gradlew :shared:testAndroidHostTest - Desktop tests:
./gradlew :shared:jvmTest - Web tests:
- Wasm target:
./gradlew :shared:wasmJsTest - JS target:
./gradlew :shared:jsTest
- Wasm target:
- iOS tests:
./gradlew :shared:iosSimulatorArm64Test
