Several visual effects implmented with Compose Multiplatform, used in 1.0 release announce video.
# Visual Effects
### Running desktop application
* To run, launch command: `./gradlew run`
* Or choose **desktop** configuration in IDE and run it.
![desktop-run-configuration.png](screenshots/desktop-run-configuration.png)
Several visual effects implemented with Compose Multiplatform, used in 1.0 release announce video.
*Prerequisites*: to run on iOS and Android, you should have "Kotlin Multiplatform Mobile" plugin installed either
in Android Studio or in AppCode with [installed CocoaPods](https://kotlinlang.org/docs/native-cocoapods.html).
## How to run
Choose a run configuration for an appropriate target in IDE and run it.
![run-configurations.png](run-configurations.png)
To run on iOS device, please correct `iosApp/Configuration/TeamId.xcconfig` with your Apple Team ID.
Alternatively, you may setup signing within XCode opening `iosApp/VisualEffects.xcworkspace` and then
using "Signing & Capabilities" tab of `VisualEffects` target.
Then choose **iosApp** configuration in IDE and run it
(may also be referred as `VisualEffects` in the Run Configurations or `iosApp (Android Studio)` for Android Studio).
## Run on desktop via Gradle
`./gradlew desktopApp:run`
