Is there any example code on how to subscribe to states and side-effects using a KMP ViewModel in Swift?

I do have one, see it here: https://github.com/GuilhE/Expressus and the step by step here:

but unfortunately orbit is not ready for KMP

I end up using https://github.com/rickclephas/KMP-ObservableViewModel or https://github.com/rickclephas/KMP-NativeCoroutines depending on the case

Sample with Shared ViewModel using KMP-ObservableViewModel:
https://github.com/GuilhE/WhosNext

Sample using KMP-NativeCoroutines only sharing data layers:
https://github.com/GuilhE/Magic

(my pref way to go)

Thank you for the post and samples ❤️

but unfortunately orbit is not ready for KMP

I briefly skimmed through your blog but couldn’t find much explanation on why Orbit isn’t ready. There’s a footnote mentioning switching to KMP-ObservableViewModel, but it doesn’t explain why.

Apologies if I missed it 🙏 ...I’ll make sure to go through your post more carefully, hopefully next week.

their gradle plugin does not support Kotlin versions > 1.6.0, last update was 4 years ago 😞

Have just started to play around with updating orbit to the latest dependencies as well supporting more native platforms.

I have initially started work on compose Multiplatform too - compiles but issues running android unit tests currently, seems to force me to run tests on an emulator/device.


After that I was going to pick up viewmodel multiplatform support and see what can be done about better Multiplatform documentation.

Hoping to have this stuff in place before KotlinConf :)
