Hello Guys, I'm working on a multi-module Kotlin Multiplatform (KMP) project targeting both iOS and Android. I'm attempting to upgrade the Kotlin version from 1.9.23 to 2.0.21, which requires the integration of the Compose Compiler Plugin. Here's the structure of my project: • Feature Modules: shared modules where ViewModel and DI logic are in commonMain. The Android UI is implemented in androidMain. • iOS UI: All iOS-specific UI code is contained within the iosApp package. After upgrading the Kotlin version, I've added the Compose Compiler Plugin to: • The root project's build.gradle file. • Each module's build.gradle file where Compose is used, including the shared feature modules. However, after making these changes: • Android builds and runs without issues. • iOS compilation fails with errors. asking for Compose Runtime dependency.(pls check image) Right now, I'm not trying to use compose code inside SwiftUI but might try to do so in the future 😅. So why iOS is failing with compose related issue
t
Have you applied new Compose Compiler Gradle Plugin?
b
Hello @tapchicoma, Yes, I did
Copy code
[versions]
kotlin = "2.0.21"
[plugins]
compose-compiler = { id = "org.jetbrains.kotlin.plugin.compose", version.ref = "kotlin" }

//root gradle
plugins {
    alias(libs.plugins.compose.compiler) apply false
    ...
}
also using convention plugin all feature modules also have the plugin compose plugin:
Copy code
class ComposeConventionPlugin: Plugin<Project> {
    override fun apply(target: Project) {
        with(target){
            with(pluginManager){
                apply(libs.findPlugin("com-google-devtools-ksp").get().get().pluginId)
                apply(libs.findPlugin("compose-compiler").get().get().pluginId)
            }
            val libraryExtension = extensions.getByType<LibraryExtension>()
            configureComposeAndroid(libraryExtension)
        }
    }
}
feature plugin
Copy code
class FeatureConventionPlugin: Plugin<Project> {
    override fun apply(target: Project) {
        with(target){
            with(pluginManager) {
                apply(libs.findPlugin("supply.base").get().get().pluginId)
                apply(libs.findPlugin("supply.compose").get().get().pluginId) // here
                apply(libs.findPlugin("supply.library").get().get().pluginId)
            }
plugins registered as:
Copy code
gradlePlugin {
    plugins {
        register("compose") {
            id = "supply.compose"
            implementationClass = "ComposeConventionPlugin"
        }
        register("feature") {
            id = "supply.feature"
            implementationClass = "FeatureConventionPlugin"
        }
here in Toml:
Copy code
supply-feature = { id = "supply.feature", version = "unspecified" }
and finally inside feature gradle:
Copy code
plugins {
    alias(libs.plugins.supply.feature)
}
t
ah, it is about compose runtime - it seems you are missing 
androidx.compose.runtime
dependency in ios source set. If you could share a Gradle build scan with error - I could check it
b
yes, I did not add 
androidx.compose.runtime
to ios source set. I should? didn't know
t
try to add it to the common dependencies
b
I added but it could not identify it. here is error from Xcode: 
all feature modules have this same error. this is just one of them

@tapchicoma well, adding composeMultiplatform and compose.runtime fixed one feature module. Now I try to add it to all feature modules. But enabling composeMultiplatform might bring other challenges🥶
Copy code
plugins {
    alias(libs.plugins.supply.feature)
    alias(libs.plugins.composeMultiplatform)
}

kotlin{
    sourceSets {
        commonMain{
            dependencies {
                api(libs.moko.paging)
                api(compose.runtime)
            }
        }
    }
}
yeah, it bring other errors 😞
Finally, problem solved. I added 
composeMultiplatform
plugin and also 
api(compose.runtime)
which brings errors: Swift cannot differenciate which @State to use. I don't know exact where it is coming from but inside my shared module there is @State. So I added @SwiftUICore before state 
@SwiftUICore.State *var* orderNavigator: OrderNavigator = .idle
now it knows. It is obviously not the best solution but for know I don't have any other solution. I'm guessing it is because of 3rd party libraries I have: moko resources moko paging moko network moko network engine moko mvvm russhwolf settings ...
