Hi All,
I am trying to use mt coroutines in my project but cannot resolve newSingleThreadContext in iosMain
• I have built https://github.com/Kotlin/kotlinx.coroutines/tree/native-mt and installed it locally
• added kotlin.mpp.enableGranularSourceSetsMetadata=true to gradle.properties
• commonMain depends on implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-common:1.3.2-native-mt-SNAPSHOT"
• iosMain depends on implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-native:1.3.2-native-mt-SNAPSHOT"
• using kotlin 1.3.61
Am I missing something?
P.S. I have also tried to build https://github.com/kpgalligan/MTCoroutines locally and it worked.

newSingleThreadContext isn’t available in common code. I think, anyway. You’d need to expect/actual.

[Aleksey Chugaev]

This is what you have in your project (iosMain):

import kotlinx.coroutines.newSingleThreadContext

@SharedImmutable
actual val workerDispatcher: CoroutineDispatcher = newSingleThreadContext("mr background")

I have copied it to my project but cannot resolve kotlinx.coroutines.newSingleThreadContext

[kpgalligan]

Ah. Do you have mavenLocal() in the repos list?

[Aleksey Chugaev]

yes, it can resolve other coroutines classes

[kpgalligan]

Well, without seeing your code, then you’re maybe pulling in a different coroutines version from another transitive dependency

[Aleksey Chugaev]

Good point, I will check other dependencies

Turns out ktor 1.3.0-beta-2 was overriding coroutines dependencies with 1.3.2-1.3.60
