Hey guys is there any way to pass environment variables to the process running Kotlin/Native iOS tests?

The following works fine for mingwX64 target:

tasks.withType<org.jetbrains.kotlin.gradle.targets.native.tasks.KotlinNativeTest> {
    environment("SOME_VAR", "some value")
}

But for some reason those are not passed when running iOS tests. Does this have to do with the fact that iOS tests run in a simulator and therefore likely start a separate process? Is there any way to pass environment variables to that other process, then?

(Note that in reality I'm setting environment() in a nested doFirst { } block because I need execution time information, but the problem occurs as well even without this peculiarity so I simplified the example)

I finally found my answer: the environment variables used by the test process are not passed to the emulator in general. However, there is a convention to pass environment variables: the SIMCTL_CHILD_ prefix.

Name a variable SIMCTL_CHILD_MYVAR and its value will be passed by simctl to the emulator as the environment variable MYVAR.
