Error message when compiling iOS framework: Unresolved reference: atomicfu. Jvm library compiles and works. Can anybody help?

I assume you’ll need to add the library dependency. I’m also not sure the atomics will do what you expect in native

I tried but from iosMain it is not visible too

[kpgalligan]

id ‘kotlinx-atomicfu’ is not native capable. You need to add atomic-fu directly as a dependency. That’s what the screenshot I shared is saying. Also, although this “compiles”, it doesn’t actually do anything atomically, if you’re hoping to interact with data from multiple threads: https://github.com/Kotlin/kotlinx.atomicfu/blob/master/atomicfu/src/nativeMain/kotlin/kotlinx/atomicfu/AtomicFU.kt

To take a step back, I guess, what are you trying to do?

[Andrey Makovskiy]

I need synchronization and AtomicReference

[Andrey Makovskiy]

in common code

[Andrey Makovskiy]

synchronized is deprecated for common 😞

[Andrey Makovskiy]

there is no volatile for common

The sample app is old, but I wrote this: https://github.com/touchlab/Stately

I feel like you should also understand how native threads work better, but I may be assuming things about your experience level with native.

[Andrey Makovskiy]

I developing multiplatform kotlin library for Android and iOS

[Andrey Makovskiy]

This library also requires threading inside

[kpgalligan]

Have you done any threading with native?

[kpgalligan]

It’s not just atomics and synchronization. State is very different

[kpgalligan]

I also have some blog posts

The 3rd one, explaining how all that works in Multiplatform, is pending a new version of Stately (which I’m currently working on)

[Andrey Makovskiy]

OK, thanks. I see that is it available in kotlin/native so I can implement it using expected/actual classes
