Hello! I am experiencing an issue in my KMP multi-...

# koin

[Guilherme Delgado]

Hello!
I am experiencing an issue in my KMP multi-module project, specifically related to DI initialization. My project includes several modules, among which core-di and data-managers . I aim to separate the DI logic within each module rather than adopting a monolithic approach. My setup in 🧵.
This setup works fine on Android, but I encounter an issue on iOS it throws a kotlin.IllegalStateException: KoinApplication has not been started.
What am I missing in the DI initialization for iOS? How can I ensure that Koin is properly initialized with this multimodule setup?

Module: data-managers
commonMain

package com.magic.data.managers
@HiddenFromObjC
expect fun diModule(): Module

androidMain

actual fun diModule() = module {
    single { CardsManager() }
}

iosMain

@OptIn(ExperimentalObjCRefinement::class)
@HiddenFromObjC
actual fun diModule() = module {
    factory { CardsManager() }
}

@Suppress("unused")
object ManagersProvider : KoinComponent {
    fun cardsManager(): CardsManager = get()
}

Module: core-di (implements data-managers )

object DependencyInjection {
    
    @Suppress("unused")
    fun initKoin() = initKoin(enableNetworkLogs = false)

    @HiddenFromObjC
    fun initKoin(enableNetworkLogs: Boolean = false, appDeclaration: KoinAppDeclaration = {}) {
        startKoin {
            appDeclaration()
            modules(
                commonModule(enableNetworkLogs = enableNetworkLogs),
                com.magic.data.managers.diModule()
            )
        }
    }
}

The relevant part of my iOS code:

import CoreDi
import DataManagers

@main
struct MagicApp: App {
    init() {
        DependencyInjection().initKoin()
        let manager = ManagersProvider().cardsManager() 
    }
    ...
}

The line let manager = ManagersProvider().cardsManager() throws a kotlin.IllegalStateException: KoinApplication has not been started.

But the same setup on Android, works.

Ok so if I apply this techinque: https://kotlinlang.org/docs/multiplatform-build-native-binaries.html#export-dependencies-to-binaries it solves 🙂
