Hi, anyone face the issue: Uncaught Kotlin exception: kotlin.IllegalStateException: KoinApplication has not been started in iOS? I have initialized koin in init() block (with swiftui) and UIApplicationDelegate (with UIkit). But ios application keep crashed. Please help me!!

[arnaud.giuliani]

in Confetti app, they have something like that:

fun initKoin(appDeclaration: KoinAppDeclaration = {}) =
    startKoin {
        modules(commonModule())
        appDeclaration()
    }

// called by iOS client
fun initKoin() = initKoin() {}

do you have the same kind of init/start function?

[Tung97 Hl]

Yes I have this setup, and I also tried both in swift ui and ui kit in ios.

There seems to be some code that is accessing your dependencies before the code that initializes them. Make sure the initKoin code is called first before anything else.

[Tung97 Hl]

Yes I think so. Compose code access my dependencies so I tried to init koin first then create ios view controller later. But it's keeping crash. Let me take a picture of my code.

Here is my code @arnaud.giuliani @Jeff Lockhart .Sorry for mentioning you guys. Please take a look
iOSApp.swift

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    
    var window: UIWindow?
    
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        KoinHelperKt.doInitKoin()
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.rootViewController = IOSMainViewKt.MainViewController()
        window?.makeKeyAndVisible()
        return true
    }
}

doInitKoin is helper function to init koin application

fun doInitKoin() = startKoin {
    modules(commonModule() + storeModule() + posSdkModule() + posTerminalSdkModule())
}

MainViewController is compose multiplatform function. I'm accessing koin dependencies inside it:

fun MainViewController(): UIViewController = ComposeUIViewController { MainScene() }

I config a logger in iOS and I see Koin already loaded but then application got crashed

[Koin]: loaded 34 definitions in 0.605958 ms
Uncaught Kotlin exception: kotlin.IllegalStateException: KoinApplication has not been started

Hi anyone can help me please:(

I'd debug by putting a break point in the dependency constructor and Koin init factory and confirm it's run before the crash. Also confirm where in your code the crash is originating from and why that's executing before Koin is initialized.
