Hello, I’ve issue with SwiftUI’s preview when using Koin, it crashes all the time when

startKoin

is invoked. The setup is: KoinHelper.kt

fun initKoin3() {
    startKoin {
    }
}

AScreen.swift

struct AScreen_Previews: PreviewProvider {
    static var previews: some View {
        let a = KoinHelperIosKt.doInitKoin3()
        AScreen()
    }
}

Here is the full crash log:

Can you show how you solved it? Struggling with the same issue.

check your implementation in iOSApp.swift & DefaultAppObservable.swift as swift’s preview provider will execute the App class. we end up put doInitKoin into App.init()
