Has anyone experienced this error, when running `embedAndSignAppleFrameworkForXcode`: (full error in thread). I’ve searched for it and the only results are someone with temporary issues related to gradle cache. This has never worked on this project, it’s not a temporary thing or a cache thing.

'org.jetbrains.kotlin.gradle.plugin.mpp.apple.EmbedAndSignTask' property 'destinationDirectory' doesn't have a configured value.

This project is a very similar setup of another project where it works fine. Both Kotlin 2.0.21, SKIE, Room, Ktor, nothing crazy

Some problems were found with the configuration of task ':shared:embedAndSignAppleFrameworkForXcode' (type 'EmbedAndSignTask').
  - In plugin 'org.jetbrains.kotlin.gradle.scripting.internal.ScriptingKotlinGradleSubplugin' type 'org.jetbrains.kotlin.gradle.plugin.mpp.apple.EmbedAndSignTask' property 'destinationDirectory' doesn't have a configured value.
    
    Reason: This property isn't marked as optional and no value has been configured.
    
    Possible solutions:
      1. Assign a value to 'destinationDirectory'.
      2. Mark property 'destinationDirectory' as optional.
    
    For more information, please refer to <https://docs.gradle.org/8.10.2/userguide/validation_problems.html#value_not_set> in the Gradle documentation.
  - In plugin 'org.jetbrains.kotlin.gradle.scripting.internal.ScriptingKotlinGradleSubplugin' type 'org.jetbrains.kotlin.gradle.plugin.mpp.apple.EmbedAndSignTask' property 'sourceFramework' doesn't have a configured value.
    
    Reason: This property isn't marked as optional and no value has been configured.
    
    Possible solutions:
      1. Assign a value to 'sourceFramework'.
      2. Mark property 'sourceFramework' as optional.

Gradle config - it works on Android. It also seems to work when assembling an xcframework file and using that manually in xcode

plugins {
     kotlin("multiplatform")
     kotlin("plugin.serialization") version "2.0.21"

        this.testLogging {

        }
    }

    val xcf = XCFramework()
    val iosTargets = listOf(iosX64(), iosArm64(), iosSimulatorArm64())

    iosTargets.forEach {
        it.binaries.framework {
            baseName = "shared"
            xcf.add(this)

    defaultConfig {
        minSdk = 26
    }

        targetCompatibility = JavaVersion.VERSION_17
    }
}

This also happens if trying to use a brand new empty KMP project(made with the KMP plugin), so my guess is some xcode config is wrong

[Aidan]

Per this message, it does look like that gradle task looks for some xcode related env variables.

Seems like it. Running assembleDebugIosFatFrameworkForSharedXCFramework instead (Which i believe is what embedAndSignAppleFrameworkForXcode does) works fine
