Should there be a version of Kotlinx Coroutines (and in particular one that supports native multithreading) available yet that works with Kotlin 1.4-M2? (I guess most KMP projects are probably blocked from using it right now anyway until various other libraries are released that work with that version)

[Kris Wong]

coroutines-native-mt is a separate preview effort

[Kris Wong]

it gets updated to the latest kotlin versions as time allows

For 1.4-M1, there is this version of kotlin coroutnes 1.3.5-native-mt-1.4-M1. Not sure if that works with M2 or has been upgraded to work with M2

[John O'Reilly]

I don't see an M2 version of that in maven at least right now

[streetsofboston]

Maybe M1 works as well….

[John O'Reilly]

Thanks, I'll give it a go tomorrow (also be nice btw if it was possible to have version that was >= 1.3.6 to allow for example use of StateFlow)

[John O'Reilly]

It also looked like there was some blockers atm preventing release of version of ktor that works with 1.4-M2 ....the plan I believe was that this release of ktor would also play nicely with native-mt version of coroutines

[Kris Wong]

yes, it's all kind of a mess ATM

[Kris Wong]

it's the biggest hindrance to being fully productive with multiplatform for android/iOS

[John O'Reilly]

actually, re-reading following update from #ktor channel it looks like issue is specifically with building native-mt version of coroutines (I had misread that earlier as indicating that issue was on ktor side)

"We have problems to build kotlinx.coroutines native-mt with 1.4-M2 kotlin right now. So the ktor native-mt will be delayed"

[kpgalligan]

ktor and everything else can take a bit to deploy after major releases, so the mt branch delay on a preview isn’t a huge surprise.

[kpgalligan]

We’re pushing out our libs for M2, but I doubt we’ll be able to do everything till next week, due to deps.

If you need it just for playing around, and don't care about reliability or quality, or that it only has JS IR support you can try my snapshot build com.ionspin.kotlin.coroutines:kotlinx-coroutines-core:1.3.5-native-mt-arm-1.4-M2-SNAPSHOT . It's on sonatype snapshot repo.

Be warned though, because the M2 release and new bugs that broke some other parts of my project, I haven't actually tried using them yet
