Anyone had problems using kotlin classes on a thread in swift, and having errors like : Uncaught Kotlin exception: kotlin.native.IncorrectDereferenceException: illegal attempt to access non-shared <object>@27c0f38 from other thread

And after trying to annotate the class with either SharedImmutable or ThreadLocal getting -> @ThreadLocal is applicable only to property with backing field, to property with delegation or to objects

You need to freeze the class before passing it around threads outside of Kotlin.

As in calling freeze() directly on Kotlin?

You can also use coroutines and the new memory model and forget about freezing objects manually
