A modern programming language that makes developers happier.

kotlinlang

Greetings! I’m currently delving into K2 in my <https://github.com/GuilhE/Expressus/tree/feature/k2|sample project>, and I’ve achieved successful compatibility with Android, iOS, and Desktop using the following versions:

- *Kotlin*: 1.9.20-Beta2
- *Ksp*: 1.9.20-Beta2-1.0.13
- *composeMultiplatformCompiler*: 1.5.2.1-Beta3

However,  when I updated to the following versions:

- *Kotlin*: 1.9.20-RC
- *Ksp*: 1.9.20-RC-1.0.13
- *composeMultiplatformCompiler*: 1.5.2.1-rc01
While Desktop functionalities remain intact - Android since there’s no compose compiler version compatible with 1.9.20-RC, I achieved success by adding `"plugin:androidx.compose.compiler.plugins.kotlin:suppressKotlinVersionCompatibilityCheck=1.9.20-RC"`) -, I encountered issues with iOS, leading to a failure.
I’ve saw the latest <https://x.com/kotlin/status/1712393112293629965?s=20|post> by Jetbrains, and I don’t know where to report my findings. If this is not the write channel, I apologize.

<@U01SRV4CQKF> I just tried with Confetti and seems to work ok (have had K2 also enabled in this project)

btw there is a dev version of androidx compose compiler now that works with 1.9.20-RC (<https://androidx.dev/storage/compose-compiler/repository>)

Let me try with those, but I’ve noticed you are using compose multiplatform 1.5.3 instead of 1.5.10-beta02 could it be that? I’m compiling to check :slightly_smiling_face:

I actually tried both and seemed ok.....looked like 1.5.3 was more recent

hmm, though version numbers may indicate otherwise

had the same problem with 1.5.3 :confused:

JetBrains team could reproduce, saw it now in the issue opened :pray:
