xcodebuild: error: SDK "iphonesimulator12.4" cannot be located

On MacOS 12.3.1 with Xcode 13.3.1.

I dowloaded the repo as a ZIP file, navigated to experimental/examples/falling-balls-mpp and ran the command ./gradlew iosDeployIPhone8Debug which game me the following error:

Although, the simulator gets open with the correct configuration.

My project is also affected by this: the Compose/iOS Gradle plugin confuses Simulator Runtimes with installed SDK's. These are not the same thing.

The SDK string is computed here:

org.jetbrains.compose.experimental.uikit.internal.RegisterConnectedDeviceTasksKt#registerConnectedDeviceTasks

...that function picks the version of the first available Simulator Runtime. Depending on the local machines Xcode setup this often results in trying to access a missing SDK and failing.

Here's a relevant Slack conversation with @dima-avdeev-jb .
