is there anyway to access the SwiftUI framework from multiplatform code? i want my iOS viewmodel to extend ObservableObject but it seems like I may not be able to access SwiftUI since there are no obj-c bridging headers

edit: change compose to swiftui - too much android on my mind

No dice here. Since Combine is Swift only, you're not going to be able to do this.

maybe i'll write some Swift code gen stuff to automatically wrap my shared viewmodels to help me here. not for today though. thanks @Thomas Myrden!

You should be able to pretty easily write some custom code to bridge a delegate pattern or similar to a pub sub pattern though. Create a protocol with an extension that does this for you or something along those lines.

No sweat, good luck!

@william in this article, you can find some code you need:

William I thought about it a lot too, basically you have 2 options:
• Introduce useCases and implement viewmodels per target (https://www.marcogomiero.com/posts/2020/kmm-shared-app-architecture/)
• Keep everything as it is and only for IOS introduce ViewModelWrappers and extend from ObservableObject and keep your view model in it.
I use second approach since I didn’t want to duplicate viewmodels per platform.
