Yeah I don’t have an iPhone 12 simulator, but why does it try running my tests on it? There are other simulators available, why does it want to use something that isn’t there?

[ribesg]

I can’t find anywhere this would be configured

[ribesg]

This worked, but I don’t know why it selects a non existing simulator without any configuration

tasks.getByName<KotlinNativeSimulatorTest>("iosX64Test") {
    deviceId = "iPhone 13"
}

It’s hardcoded I believe: https://github.com/JetBrains/kotlin/blob/c777ecd470c7465cd7b6a3a49b78e584198d84f5/kotlin-native/build-tools/src/main/kotlin/org/jetbrains/kotlin/ExecutorService.kt#L275

(but it’s 11 there, not 12 🤯 )

[ribesg]

Yeah so it’s not that. It’s also my first implementations of tests in this project and they never ran on anything but an iPhone 13 simulator so it’s weird.

Did you find out what was the problem? I have the same issue

[ribesg]

No, I have an existing simulator manually configured as above everywhere I have iOS tests

thanks 🙂
