Unable to resolve dependency in Kotlin MPP

[RomeuG]

Hello.

I am trying to integrate this library into a project and in iOS, Gradle gives the following error:

Could not determine the dependencies of task ':project:linkDebugFrameworkIosArm32'.
> Could not resolve all task dependencies for configuration ':project:iosArm32CompileKlibraries'.

My Gradle file, although being in Groovy, it seems to be pretty much correct?

    //iosBaseLocalizationRegion = "en" //optional, default "en"

}

I also have enableFeaturePreview("GRADLE_METADATA") in my settings.gradle, removing it causes some problems. Also, it works well on Android.

Any clues?

Thanks

Fixed.

It seems that changing the ios project related stuff to this

// ios
    if (project.findProperty("kotlin.native.cocoapods.target") == "ios_arm") {
        iosArm64('ios') {
            binaries {
                framework('Common')
            }
        }
    } else {
        iosX64('ios') {
            binaries {
                framework('Common')
            }
        }
    }

and adding an xcode packing task:

task packForXcode {
    def buildType = project.findProperty("kotlin.build.type") ?: "DEBUG"
    def target = project.findProperty("kotlin.target") ?: "ios"
    def framework = kotlin.targets."$target".compilations
            .main.target.binaries.findFramework("Common", buildType)

    dependsOn framework.linkTask

    doLast {
        copy {
            from framework.outputFile.parent
            into framework.outputFile.parentFile
            include 'data.framework/**'
            include 'data.framework.dSYM'
        }
    }
}

Fixed the issue.
