Introduces DataManagerEnvironmentKey + EnvironmentValues.dataManager so SwiftUI views can resolve DataManagerObservable via @Environment, mirroring Compose's LocalDataManager ambient on the Kotlin side. No view migrations yet — views continue to read DataManagerObservable.shared directly. The actual screen-level substitution (fake DataManager for parity-gallery / tests / previews) lands in P1 when ViewModels gain an optional init param that accepts the environment-resolved observable. For this commit we only need the key so P1 can wire against it. Note: the iosSimulator Kotlin compile is broken at baseline (bb4cbd5) with pre-existing "Unresolved reference 'testTagsAsResourceId'" errors across 20+ screen files — Android-only semantics API imported in commonMain. Swift-parse of the new file succeeds. Verified by checking outbb4cbd5and rerunning ./gradlew :composeApp:compileKotlinIosSimulatorArm64.

This is a Kotlin Multiplatform project targeting Android, iOS, Web, Desktop (JVM).
-
/composeApp 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.
-
/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.
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 :composeApp:assembleDebug - on Windows
.\gradlew.bat :composeApp:assembleDebug
Build and Run Desktop (JVM) Application
To build and run the development version of the desktop app, use the run configuration from the run widget in your IDE’s toolbar or run it directly from the terminal:
- on macOS/Linux
./gradlew :composeApp:run - on Windows
.\gradlew.bat :composeApp:run
Build and Run Web Application
To build and run the development version of the web app, use the run configuration from the run widget in your IDE's toolbar or run it directly from the terminal:
- for the Wasm target (faster, modern browsers):
- on macOS/Linux
./gradlew :composeApp:wasmJsBrowserDevelopmentRun - on Windows
.\gradlew.bat :composeApp:wasmJsBrowserDevelopmentRun
- on macOS/Linux
- for the JS target (slower, supports older browsers):
- on macOS/Linux
./gradlew :composeApp:jsBrowserDevelopmentRun - on Windows
.\gradlew.bat :composeApp:jsBrowserDevelopmentRun
- on macOS/Linux
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 /iosApp directory in Xcode and run it from there.
