Xcode preview not working #27

Closed kansson closed 1 year ago

kansson commented 1 year ago

Hello, awesome project!

I'm using this package together with NativeCoroutines and everything works great on both platforms but not in the Xcode preview. The preview will not load at all and crashes with this error log.

The code that crashed the preview is this view binding of a view model. If it's removed the preview works.

struct ContentView: View {
    @ObservedViewModel var viewModel = SharedModule().homeViewModel

    var body: some View {
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundColor(.accentColor)
            Text(viewModel.state.query)
        }
        .padding()
    }
}

I'm using Koin for dependency injection and I've confirmed it's not the issue as this code works in the preview.

struct ContentView: View {
    var body: some View {
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundColor(.accentColor)
            Text(SharedModule().homeViewModel.state.query)
        }
        .padding()
    }
}

Have been looking for similar problems and found this https://github.com/JetBrains/kotlin-native/issues/3059#issuecomment-501699248. Maybe this could help with solving this problem?

Hi! Thanks for reporting this. I just checked with the sample project which has working SwiftUI previews. Could you possibly share some more details about your project setup?

kansson commented 1 year ago

Sure here is a reproduction https://github.com/hanssonduck/XcodePreview. Now when I'm looking at it maybe this package isn't the problem.

What I did was delete the default Xcode project and created a new Xcode multiplatform project and then linking it with Kotlin following this https://kotlinlang.org/docs/multiplatform-mobile-integrate-in-existing-app.html#connect-the-framework-to-your-ios-project. Seems that maybe I did something wrong here. New to Xcode and Swift development so not sure, maybe you can see something. You can compare the two commits to see the working and broken states.

TLDR: Generated new multiplatform Xcode project that broke the preview.

Hi again, got it working with this solution https://stackoverflow.com/a/71214308/10055887. Not sure what the problem is but it works and I'm happy. If you do find something of interest feel free to mention it nonetheless.
