kotlin.native.internal.FileFailedToInitializeException: There was an error during file or class initialization

Strings.kt: package com.qvc.kmp.poc.shared

import dev.icerock.moko.resources.StringResource import dev.icerock.moko.resources.desc.Resource import dev.icerock.moko.resources.desc.StringDesc import dev.icerock.moko.resources.format

actual class Strings { actual fun get(id: StringResource, args: List<Any>): String { return if(args.isEmpty()) { StringDesc.Resource(id).localized() } else { id.format(*args.toTypedArray()).localized() } } }

SwiftUi: Text( Strings().get(id: SharedRes.strings().product_description, args: []) )

Function doesn't have or inherit @Throws annotation and thus exception isn't propagated from Kotlin to Objective-C/Swift as NSError. It is considered unexpected and unhandled instead. Program will be terminated. Uncaught Kotlin exception: kotlin.native.internal.FileFailedToInitializeException: There was an error during file or class initialization

Can someone help here ?

your error can be related to #796 that will be fixed in 0.24.5. or it can be just misconfiguration if you use static framework and not call copyResources task from xcode.

[MartinStrambach]

I assume @sunilhs1986 has the same problem as I do. The configuration of my modularized project is as follows:

• Core framework where I link static multiplatform framework ./gradlew :shared:embedAndSignAppleFrameworkForXcode
• Application target where I run "$SRCROOT/../gradlew" -p "$SRCROOT/../shared" :shared:copyFrameworkResourcesToApp

This configuration still crashes with 0.24.5 with the same error. When I move copyFrameworkResourcesToApp to Core framework it works. @Alex009 Is this behaviour as intented?

[Alex009]

@MartinStrambach looks like not intended. copyFrameworkResourcesToApp should be called for module that produce static framework. can you give me reproducer project to debug?

I am getting kotlin.native.internal.FileFailedToInitializeException when running iOS tests that use Moko-resources. I am not sure if this is related or it's something totally different.

Project Structure

I have the following modular structure.

i18n/
├── api/            # API interfaces
├── generator/      # Moko-resources generator module with the configuration
├── implementation/ # Implementation with localizers
└── testing/        # Testing utilities

// i18n/generator/build.gradle.kts

.....
multiplatformResources {
    resourcesPackage.set("com.thomaskioko.tvmaniac.i18n")
}

Test Setup

Test Class Structure

// MokoLocalizerTest.kt
class MokoLocalizerTest : BaseResourceTests() {
    @Test
    fun `should return localized string for valid key`() {
        val result = localizer.getString(StringResourceKey.ButtonErrorRetry)
        result shouldBe "Retry"
    }

    @Test
    fun `should return formatted string when arguments are provided`() {
        val result = localizer.getString(CdShowPosterImage, "Breaking Bad")
        result shouldBe "Poster image for Breaking Bad"
    }
}

iOS Test Implementation

// BaseResourceTests.kt (iOS)
actual abstract class BaseResourceTests : BaseLocalizerTest() {
    actual val localizer: Localizer
        get() = MokoResourcesLocalizer(PlatformLocalizer())
}

Additional Context

• The same tests work fine on Android and JVM targets
• The issue specifically affects iOS testing

I am having the same issue when upgraded to 0.25.0.

My libraries versions before the upgrade:

agp = "8.2.2" gradleTools = "7.2.2" kotlin = "2.0.21"

activityCompose = "1.9.2" androidXCore = "1.13.1" appCompat = "1.7.0" buildConfig = "5.3.5" coilCompose = "2.7.0" compose = "1.6.8" mapsCompose = "5.0.4" composeMultiplatform = "1.6.11" coroutines = "1.9.0" credentials = "1.3.0" fragmentKtx = "1.8.5" gmsAuth = "20.0.1" gmsAuthApiPhone = "17.4.0" googleMaterial = "1.12.0" imageLoader = "1.6.6" junit = "4.13.2" ktor = "2.3.13" kotlinxSerialization = "1.7.3" kotlinxDatetime = "0.6.0" libPhoneNumber = "8.13.52" lifecycle = "2.8.5" material3 = "1.3.1" mokoGeo = "0.7.0" mokoGraphics = "0.9.0" mokoParcelize = "0.9.0" mokoPermissions = "0.18.0" mokoResources = "0.24.3" okio = "3.9.1" precompose = "1.6.2"

realm = "2.3.0" swipeRefresh = "1.1.0" viewmodelCompose = "2.8.0" playServicesMaps = "19.0.0"

And after:

agp = "8.6.0" gradleTools = "7.2.2" kotlin = "2.2.0"

activityCompose = "1.10.1" androidXCore = "1.16.0" appCompat = "1.7.1" buildConfig = "5.6.8" coilCompose = "2.7.0" compose = "1.9.1" mapsCompose = "5.0.4" composeMultiplatform = "1.8.2" composeNavigation = "2.9.0" coroutines = "1.8.0" fragmentKtx = "1.8.9" gmsAuth = "21.4.0" gmsAuthApiPhone = "18.2.0" googleMaterial = "1.13.0" imageLoader = "1.10.0" junit = "4.13.2" ktor = "2.3.13" kotlinxSerialization = "1.9.0" kotlinxDatetime = "0.6.0" libPhoneNumber = "8.13.52" lifecycle = "2.9.3" lifecycleCompose = "2.9.4" material3 = "1.3.2" materialIcons = "1.7.8" mokoGeo = "0.8.0" mokoGraphics = "0.9.0" mokoParcelize = "0.9.0" mokoPermissions = "0.19.1" mokoResources = "0.25.0" okio = "3.10.2"

realm = "3.2.8-2" swipeRefresh = "1.1.0" viewmodelCompose = "2.9.4" playServicesMaps = "19.2.0"

But I tested a lot of options and it's always the same. For the imageLoader (io.github.qdsfdhvh:image-loader) and moko-graphics I tried also to remove them because I noticed that they depend on moko-resources but it's still the same so maybe it's about the library itself or something about my configuration. Let me know what can I check or if you need some additional information. It is about iOS, the android build works correctly
