Did anyone found a workaround for the problem that currently you can't create XCFrameworks containing macOS X64 & ARM64 with Kotlin 1.5.30?

It's an open issue and somewhere in the roadmap.
https://youtrack.jetbrains.com/issue/KT-47355

What are my options to work around that limitation?

I tried to export it as a separate XCFramework / framework and combine it with the lipo command but no success.

Reason is different file layout for macos frameworks.
Yes, it hasn’t been supported yet

Strange. If I build for macOS X64 only it works and macOS ARM64 only also works.
If iOS X64 and ARM64 are both selected they go into different folders.

So it's not just a matter of adding a "macos-x64" folder here and add an entry to the Info.plist ?

[Konstantin Tskhovrebov]

yes, because same targets with different architectures must be packed to fat framework

[Stefan Oltmann]

This sounds to me like an intermediate step that could be skipped. AFAIK are fat frameworks the old way of doing that. If I know have X frameworks I can directly merge them into a XCFramework or couldn't I?

... ok... I have a hard time understanding this whole mess apple created there and hope you find a solution to make it work 😄

For a workaround: Can I export my macosX64 separate and try to lipo it together?
After discarding my custom fat framework solution in exchange for the official way with assembleSharedReleaseXCFramework I fail to see how I can export my macosX64 framework.

My code looks like this:

val xcf = XCFramework()

/* App Store */
iosArm64 {
    binaries.framework {
        baseName = "shared"
        embedBitcode("bitcode")
        xcf.add(this)
    }
}

/* iOS Simulator M1 */
iosSimulatorArm64 {
    binaries.framework {
        baseName = "shared"
        xcf.add(this)
    }
}

/* Intel macOS Devices */
macosX64 {
    binaries.framework {
        baseName = "shared"
        // xcf.add(this)
    }
}

/* Apple Silicon macOS Devices */
macosArm64 {
    binaries.framework {
        baseName = "shared"
        xcf.add(this)
    }
}
