Up to now I've used Ktor 3.0.0-wasm1 version in isolated module but trying it now in common code in a KMP project.....it seems to mostly work but on iOS I'm getting following....I have added atomicfu in dependencies but perhaps might be using wrong version (also using coroutines 1.8.0-RC)

w: skipping /Users/joreilly/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlinx/atomicfu-iossimulatorarm64/0.23.1/577e14084dac4dbadcaf86db01f359b4939f5d5a/atomicfu-cinterop-interop.klib. The library versions don't match. Expected '0.22.0-wasm2', found 'unspecified'

@John O'Reilly please try to specify explicitly atomicfu as dependency, as workaround

[John O'Reilly]

Yeah, I have that but still getting that error.....perhaps using wrong version.....what version should I have?

[John O'Reilly]

have this right now

implementation("org.jetbrains.kotlinx:atomicfu:0.23.1")

[Igor Yakovlev]

I made a simple project and for me seems everything works well. Could you please to send me a small repro to check it on my side? (please notice, that ktor you use is not published in the main channel yet and its highly experimental).

[John O'Reilly]

will do, is that the version of atomicfu you're using btw?

[John O'Reilly]

could you also share commonMain dependencies you have there?

[Igor Yakovlev]

val commonMain by getting {
    dependencies {
        implementation("io.ktor:ktor-client-core:3.0.0-wasm1")
        implementation("io.ktor:ktor-client-cio:3.0.0-wasm1")
    }
}

val commonTest by getting {
    dependencies {
        implementation(kotlin("test"))
    }
}

[John O'Reilly]

ok, so you didn't need to specify atomicfu dependency explicitly?

[John O'Reilly]

thought that was needed due to https://github.com/Kotlin/kotlinx.coroutines/issues/3968

[John O'Reilly]

(when using 1.8.0-RC of kotlinx coroutines)

[Igor Yakovlev]

this is a bug with dependency for native targets, which is not connected with wasm or ktor

[John O'Reilly]

I see issue here then if running say (used kmp.jetbrains.com to generate project)

./gradlew :composeApp:compileKotlinIosSimulatorArm64

[John O'Reilly]

I thought maybe ktor was coming in to picture here due to some dependency it had on atomicfu (given expected '0.22.0-wasm2' in error above)

[John O'Reilly]

should be able to use https://github.com/joreilly/ClimateTraceKMP to reproduce error

[Andrey Larionov]

@John O'Reilly Hi, did you fix it? I mention about it at KT-64111 issue

[John O'Reilly]

No, not yet

[John O'Reilly]

looks like same issue I'm seeing at least

[Andrey Larionov]

@Igor Yakovlev @bashor Hello. I created a simple project and you can test this error. Steps:
1. Go to gist and run a simple local Flask server (pip install flask & pip install flask_cors required)
2. Clone this repo and run any configuration except iOS to be sure that everything works fine
a. For Desktop or Web configurations, change 10.0.2.2 to localhost
b. I ran Android configuration on Emulator so I needed to use 10.0.2.2 proxy (because localhost provides emulator in this case)
3. Run iOS configuration
P.S. Yes, I tried to specify explicitly atomicfu as dependency, but it doesn’t work

[Igor Yakovlev]

I published ktor 3.0.0-wasm2 into experimental repository which is not affected to this issue.

[Andrey Larionov]

Could not find io.ktor:ktor-client-core:3.0.0-wasm2
Could not find io.ktor:ktor-client-content-negotiation:3.0.0-wasm2
Could not find io.ktor:ktor-serialization-kotlinx-json:3.0.0-wasm2

[John O'Reilly]

@Igor Yakovlev it looks all right like it's only been published for some artefacts e.g. it's not there for https://maven.pkg.jetbrains.space/kotlin/p/wasm/experimental/io/ktor/ktor-client-core/

[Igor Yakovlev]

Yeah…something went wrong. I will republish it soon

[John O'Reilly]

I notice there's a 3.2.0 version there (and have been getting renovate notifications about that version today for various repos)....assume that's a mistake?

[Andrey Larionov]

@John O'Reilly If you use Kotlin/Wasm you should use :wasm version everywhere it’s possible
I guess if your project includes only Android, iOS and Desktop configurations, you can use the lates available version eg 3.2.0
By the way, you can easily check it by creating a simple project via Kotlin Multiplatform Wizard without a Web configuration

[John O'Reilly]

@Igor Yakovlev I'm seeing all needed 3.0.0-wasm2 ktor dependencies available now, thanks!

[John O'Reilly]

And confirmed iOS client is building/running now as well.
