How long will it take for Kotlin 2.1.0 to be adapted?

[TadeasKriz]

I'm not sure what you mean, but SKIE supports Kotlin 2.1.0 since the 0.9.5 release.

[coreypett-cube]

Kotlin 2.1.0 was the source of our SIGSEV related crashes on our iOS 18 SwiftUI app.

We reverted everything back to Kotlin 2.0.21 to resolve this.

I am unsure if this is related to SKIE. But, maybe @xuegao-tzx question was more general than specific to SKIE.

Has anybody else noticed this on Kotlin 2.1.0?

[coreypett-cube]

Maybe I should try the Swift Export for Kotlin 2.1.0.. 🤔

[TadeasKriz]

That's interesting. I see it crashes at -[KotlinBase hash], which shouldn't have anything to do with SKIE. Could you share more about the code that crashes for you?

Swift Export for Kotlin 2.1.0 is very limited and I wouldn't expect it to be usable for any general app.

Good to know, thank you

Could you share more about the code that crashes for you?

The project has grown quite a bit, and I suspect one of our ForEach statements somewhere is to blame.
Once I have some downtime, I'll revisit this and debug.

I just wanted to share. Skie has made our KMP life much easier <3

@TadeasKriz the documentation is still on 2.0.1: https://skie.touchlab.co/intro#getting-started

I think this is where some of the confusion is coming from. Can those docs be updated?
