 # Compose Multiplatform benchmarks

 ## Run Desktop
- `./gradlew :run`
+- `./gradlew :benchmarks:run`
+
+## Run native on iOS
+Open the project in Fleet or Android Studio with KMM plugin installed and 
+choose `iosApp` run configuration. Make sure that you build the app in `Release` configuration.
+Alternatively you may open `iosApp/iosApp` project in XCode and run the app from there.

 ## Run native on MacOS
- - `./gradlew runReleaseExecutableMacosArm64` (Works on Arm64 processors)
- - `./gradlew runReleaseExecutableMacosX64` (Works on Intel processors)
+ - `./gradlew :benchmarks:runReleaseExecutableMacosArm64` (Works on Arm64 processors)
+ - `./gradlew :benchmarks:runReleaseExecutableMacosX64` (Works on Intel processors)

 ## Run in web browser:

@ -13,4 +18,4 @@ Please run your browser with manual GC enabled before running the benchmark, lik

 `open -a Google\ Chrome --args --js-flags="--expose-gc"`

- `./gradlew wasmJsBrowserProductionRun` (you can see the results printed on the page itself)
