0.30.0 kotlinx.coroutines does not seem to compile with iOS

I followed the Intellij IDEA File->New Project-> (Kotlin Tab) -> Kotlin (Mobile Android/iOS) generator tool to setup a project for testing a shared codebase between iOS and Android.

The coroutine setup works well for android but for some reason I can’t get a clean build for iOS with the following setup:

kotlin {
    targets {
        // For ARM, preset should be changed to presets.android_arm32 or presets.android_arm64
        fromPreset(presets.android, 'android')
        // For ARM, preset should be changed to presets.iosArm32 or presets.iosArm64
        fromPreset(presets.iosX64, 'ios')
    }
    sourceSets {
        commonMain {
            dependencies {
                implementation 'org.jetbrains.kotlin:kotlin-stdlib-common'
                implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-common:$coroutines_version"
            }
        }
        commonTest {
            dependencies {
        		implementation 'org.jetbrains.kotlin:kotlin-test-common'
        		implementation 'org.jetbrains.kotlin:kotlin-test-annotations-common'
            }
        }
        androidMain {
            dependencies {
                implementation 'org.jetbrains.kotlin:kotlin-stdlib-jdk8'
                implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:$coroutines_version"
            }
        }
        androidTest {
            dependencies {
                implementation 'org.jetbrains.kotlin:kotlin-test'
                implementation 'org.jetbrains.kotlin:kotlin-test-junit'
                implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:$coroutines_version"
            }
        }
        iosMain {
            dependencies {
                implementation 'org.jetbrains.kotlin:kotlin-stdlib-common'
                implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-common:$coroutines_version"
            }
        }
        iosTest {
            dependencies {
                implementation 'org.jetbrains.kotlin:kotlin-stdlib-common'
                implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-common:$coroutines_version"
            }
        }
    }
}

I get the following exception:

> Task :proj

                         ^

FAILURE: Build failed with an exception.

I do assume I did something wrong, but I i’ve tried using both native+common as dependency for iOS but it does not accept it. Can someone point me towards the right direction?

@Syrou try to add enableFeaturePreview('GRADLE_METADATA') in settings.gradle

Thanks for the reply @wild-lynx As stated below my code snippet I did try with “kotlinx-coroutines-core-native” as dependency as well without any success.

The KotlinConf app uses an older setup than the one specified in https://kotlinlang.org/docs/tutorials/native/mpp-ios-android.html, and from my tests only work if you use the -conf2 on the two more important dependencies, and I do not want to go back to something that is not gonna work with the 1.3.0RC/1.3.0

Try cloning the KotlinConf app and bump the versions up to the latest releases and you will notice it does not work anymore.
