Followed https://github.com/rickclephas/KMP-ObservableViewModel?tab=readme-ov-file#swift but got this error: Type 'Kmp_observableviewmodel_coreViewModel' does not conform to protocol 'ObservableObject'

Kotlin: 2.2.10
KMP-ObservableViewModel: 1.0.0-BETA-13
Xcode: 26.0 (17A324)

Hi. Could you possibly share the code snippet that triggers this error?

Hi. Could you possibly share the code snippet that triggers this error?

Yes sorry, here:

package package.shared.viewmodel

import package.shared.repository.AuthRepository
import com.rickclephas.kmp.observableviewmodel.ViewModel
import com.rickclephas.kmp.observableviewmodel.stateIn
import kotlinx.coroutines.flow.SharingStarted
import kotlinx.coroutines.flow.distinctUntilChanged
import kotlinx.coroutines.flow.map
import org.koin.android.annotation.KoinViewModel

sealed class AppState {
    data object Loading : AppState()
    data object Data : AppState()
}

@KoinViewModel
class AppViewModel internal constructor(
    authRepository: AuthRepository,
) : ViewModel() {
    val state = authRepository.me()
        .distinctUntilChanged()
        .map { AppState.Data }
        .stateIn(
            viewModelScope = viewModelScope,
            started = SharingStarted.WhileSubscribed(),
            initialValue = AppState.Loading,
        )
}

import KMPObservableViewModelCore
import Shared

extension Kmp_observableviewmodel_coreViewModel: @retroactive ViewModel {}

Update: it works if you import Combine in the Swift file.

Sorry for the delay. I wasn't able to reproduce this just yet.
But I am glad to hear adding the Combine import resolves the issue 👍🏻.
