Hi, I'm currently working on a compose multiplatform chart library. It's already on mavenCentral (snapshot version). On Android, the app builds and runs without any issues. However, on iOS the build fails with

> Task :shared:linkDebugFrameworkIosSimulatorArm64 FAILED
error: Could not find "Compose" in [/Users/max/StudioProjects/compose-multiplatform-pomodoro, /Users/max/.konan/klib, /Users/max/.konan/kotlin-native-prebuilt-macos-aarch64-1.9.10/klib/common, /Users/max/.konan/kotlin-native-prebuilt-macos-aarch64-1.9.10/klib/platform/ios_simulator_arm64]

And this is the build.gradle file of the library:

plugins {
    alias(libs.plugins.kotlin.multiplatform)
    alias(libs.plugins.android.library)
    alias(libs.plugins.compose.multiplatform)
    id("maven-publish")
    id("signing")
    id("com.vanniktech.maven.publish") version "0.25.3"
}

kotlin {
    androidTarget {
        compilations.all {
            kotlinOptions {
                jvmTarget = "17"
            }
        }

        publishLibraryVariants("release", "debug")
    }

    ios{}
    iosX64()
    iosArm64()
    iosSimulatorArm64()

    sourceSets {
        val commonMain by getting {
            dependencies {
                api(compose.runtime)
                api(compose.foundation)
                api(compose.material3)
                api(compose.animation)

                implementation(libs.kotlinx.atomicfu)
            }
        }
        val commonTest by getting {
            dependencies {
                //implementation(libs.kotlin.test)
            }
        }
        val iosX64Main by getting
        val iosArm64Main by getting
        val iosSimulatorArm64Main by getting
        val iosMain by getting {
            dependsOn(commonMain)
            iosX64Main.dependsOn(this)
            iosArm64Main.dependsOn(this)
            iosSimulatorArm64Main.dependsOn(this)
        }
    }
}

android {
    namespace = "..."

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }
    kotlin {
        jvmToolchain(17)
    }

    compileSdk = 34
    defaultConfig {
        minSdk = 26
    }
}

mavenPublishing {
    ...
}

In the app, which uses the library, I simply have added it as a commonMain dependency:

api(libs.compose.multiplatform.chart)

What could be the problem here? Why doesn't the task find "Compose"?

Are this library open source? Can you please share a link to sources.

Can you tell maven coordinates of your library?

yes, the source code is on GitHub (you can ignore the readme, it needs to be updated): https://github.com/maximilianproell/compose-multiplatform-chart Current version is "2.0.2-SNAPSHOT"

I haven't pushed the added dependency though, as the app doesn't build for iOS

So what line should I add to reproduce the problem?

Add

implementation("io.github.maximilianproell:compose-multiplatform-chart:2.0.2-SNAPSHOT")

to

commonMain

of any KMP project targeting Android and iOS, observe that the Android App builds and runs successfully, whereas the iOS version does not build, throwing the error message mentioned above.
