A modern programming language that makes developers happier.

kotlinlang

I'm trying to use CIO and I'm just getting around to running my iOS app.  I'm seeing this illegal state exception and I'm wondering if there is a flag I'm missing that will allow me to use it?  Should I not use it all until it gets out of the experimental phase?

You can only use the new memory model with CIO

```kotlin.native.binary.memoryModel=experimental
kotlin.native.binary.freezing=disabled```


I’ve been using the new mm for months with no issues. I switched over during the first dev preview in 1.6

Can you point me to the docs on how to switch to the new memory model.  I assume there is more to it than those two lines?

<https://github.com/JetBrains/kotlin/blob/master/kotlin-native/NEW_MM.md>

Should just be the two lines. There’s more you can add if you want to debug the mm in that article.

I would also add `kotlin.native.cacheKind=none`  for now, since caching can be iffy with the new mm right now.
