In a multiplatform module, I would like to use Compose for Android and Desktop in a shared source set (javaMain ), but keep assembling a normal iOS framework (to be consumed from an XCode project with SwiftUI), and also use Kotlin/React for UI in jsMain . I managed to put the Compose code into javaMain and android and desktop target compile just fine. I also managed to disable the Compose plugin for JS by adding compose.web.targets(), and it also compiles just fine. But I can't find a way to disable the Compose plugin for iOS. My iOS build fails with:

Compilation failed: Cannot find the Composer class in the classpath

Is there any workaround? I'm using Compose 1.1.1.

Experienced the same issue too, and worked around it by adding the following to the build.gradle.kts file:

configurations.all {
    // Exclude native compiler
    exclude("org.jetbrains.compose.compiler", "compiler-hosted")
}

Works for me but not sure if it can cause any other issues

[Arkadii Ivanov]

Thanks, I will try!

Got the idea from here by the way: https://github.com/JetBrains/compose-jb/blob/3221d7c3069c92a294e91aa9bd24e87e8eb55[…]lin/org/jetbrains/compose/ComposeCompilerKotlinSupportPlugin.kt

Looks like that workaround no longer works with Kotlin 1.7.0

[Thomas]

Right, I am using a different workaround now

import org.jetbrains.compose.ComposeCompilerKotlinSupportPlugin
import org.jetbrains.kotlin.gradle.plugin.KotlinCompilation
import org.jetbrains.kotlin.gradle.plugin.KotlinCompilerPluginSupportPlugin
import org.jetbrains.kotlin.gradle.plugin.KotlinPlatformType

plugins {
    // ... other plugins
    id("org.jetbrains.compose") version "1.2.0-alpha01-dev741"
}

// Exclude native compiler
plugins.removeAll { it is ComposeCompilerKotlinSupportPlugin }
class ComposeNoNativePlugin : KotlinCompilerPluginSupportPlugin by ComposeCompilerKotlinSupportPlugin() {
    override fun isApplicable(kotlinCompilation: KotlinCompilation<*>): Boolean {
        return when (kotlinCompilation.target.platformType) {
            KotlinPlatformType.native -> false
            else -> ComposeCompilerKotlinSupportPlugin().isApplicable(kotlinCompilation)
        }
    }
}
apply<ComposeNoNativePlugin>()

[Thomas]

That works, it hasn’t gotten any prettier but it does the job

[Thomas]

If you find anything better please share!

Wow thanks a lot! Works like a charm!
