Hello :wave: We have a kmm project and it was all ...

Hello 👋
We have a kmm project and it was all good until we tried to run it on Xcode 14 😅

iOS is calling a shared api which is a suspend function. It was working fine till now but crashes in Xcode 14 with
Uncaught Kotlin exception: kotlin.native.IncorrectDereferenceException: illegal attempt to access non-shared

Shared kotlin code:

open val content: suspend () -> Content =
            { getContent() }

getContent() calls other suspend function to retrieve data from local cache.

iOS code:

func getContent() async -> Content {
    await sharedGetApi.content.execute() //accessing shared `content` here.
}


extension KotlinSuspendFunction0 {
    func execute<T>() async -> T {
        do {
            let result: T? = try await self.invoke() as? T
            if let result = result {
                return result
            } else {
                fatalError("\(T.self) can not be nil")
            }
        } catch {
            fatalError(error.localizedDescription)
        }
}

library versions:
coroutines = "1.6.3"
kotlin = "1.6.10"

Any help would be appreciated 🙏
TIA

Are you using coroutines -mt? This might sound like you are missing to manually activate new memory model.

If it is feasible for you, you can upgrade to kotlin 1.7 which enables new mm by default.
