why kotlin multiplatform don't execute and export iOS framework?

I started develop kotlin multiplatform and I developed a simple lib for test. I can exported .jar file for android but I can't export .framework file for iOS. I reviewed other project but I didn't find my issue.

my Gradle script for lib is:

apply plugin: 'kotlin-multiplatform'

kotlin {
targets {
    final def iOSTarget = 
    System.getenv('SDK_NAME')?.startsWith("iphoneos") \
                          ? presets.iosArm64 : presets.iosX64

    fromPreset(iOSTarget, 'iOS') {
        compilations.main.outputKinds('FRAMEWORK')
    }

    fromPreset(presets.jvm, 'android')
}

sourceSets {
    core.dependencies {
        api 'org.jetbrains.kotlin:kotlin-stdlib-common'
    }

    android.dependencies {
        api 'org.jetbrains.kotlin:kotlin-stdlib'
    }
}

What do you mean by "exporting a framework"? Are you going to use it from another Gradle project or from XCode or from something else?

P.S. Sorry for asking in answers: just have no enough reputation to leave a comment. So I think it would be more convenient to discuss you problem in issues at GitHub.

Have you added the task to build the actual framework? If not, try adding this code at the end of your build.gradle file:

task packForXCode(type: Sync) {
    final File frameworkDir = new File(buildDir, "xcode-frameworks")
    final String mode = project.findProperty("XCODE_CONFIGURATION")?.toUpperCase() ?: 'DEBUG'

    inputs.property "mode", mode
    dependsOn kotlin.targets.iOS.compilations.main.linkTaskName("FRAMEWORK", mode)

    from { kotlin.targets.iOS.compilations.main.getBinary("FRAMEWORK", mode).parentFile }
    into frameworkDir

    doLast {
        new File(frameworkDir, 'gradlew').with {
            text = "#!/bin/bash\nexport 'JAVA_HOME=${System.getProperty("java.home")}'\ncd '${rootProject.rootDir}'\n./gradlew \$@\n"
            setExecutable(true)
        }
    }
}

tasks.build.dependsOn packForXCode

The iOS framework will be available on the build/xcode-frameworks directory of your library.

You'll have to configure also your Xcode project to use the framework. For further details you can read Setting up Framework Dependency in Xcode.
