Is coroutines supported in Kotlin/Native or CommonMain modules?

[Sam]

Yes but limited to both questions.

[Sam]

In native, coroutines can only run on the main thread. In Common there is no runBlocking because not all targets are multi-threaded (Javascript).

[Kruger Brent]

But I am unable to use them in iOS or common target. Import works only in Android Activity

[Jeremy]

Yes but they are limited. Can you show example code and build.gradle?

[Kruger Brent]

build.gradle of SharedLib module

[Kruger Brent]

iosMain/actual.kt file

[Kruger Brent]

build.gradle of app module, that has coroutines imported and works fine in Android MainActivity.kt

[Kruger Brent]

@Jeremy I have posted the screenshots. Please let me know what I am doing wrong here!

[Jeremy]

Are you getting compiler errors or only in IDE? IDE support isn't complete (yet)

[Kruger Brent]

I am getting compilation errors

[Jeremy]

You need to include the coroutines in the common dependencies

[Jeremy]

in common

[Jeremy]

implementation "org.jetbrains.kotlinxkotlinx coroutines core common$coroutines_version"
implementation "org.jetbrains.kotlinxkotlinx coroutines test$coroutines_version"

[Kruger Brent]

Okay, let me try that

[Jeremy]

and in ios use: implementation "org.jetbrains.kotlinxkotlinx coroutines core native$coroutines_version"

[Jeremy]

Heres a more complete example: https://raw.githubusercontent.com/jeremyrempel/gitnotes/master/lib/build.gradle

[Kruger Brent]

Let me take a look at that

[Jeremy]

Np also see https://github.com/Kotlin/kotlinx.coroutines/blob/master/README.md covers the setup

[Kruger Brent]

It works in the common module

[Kruger Brent]

iOS still doesn’t work

[Kruger Brent]

I referred to those links you shared. Those were helpful. But for me serialization is giving trouble as well. “Plugin with id ‘kotlinx-serialization’ not found”

[Jeremy]

You setup the ios specific coroutine dependency to your gradle?

[Kruger Brent]

yes, I did

[Kruger Brent]

the core-native one

[Kruger Brent]

the file looks like this now

[Jeremy]

KN coroutine doesn't have GlobalScope, you need to pass coroutine context in from native iOS

Thank you Chris, I will take a look!
