Framework was build without full bitcode

I have an iOS dynamic framework built using Kotlin Multiplatform. I can successfully link against it, build and run with it. However, when archiving, Xcode throws the error: ld: bitcode bundle could not be generated because '/path/to/framework' was built without full bitcode. The following rule is used in our build.gradle.kts file for the framework:

iosArm64 {
    binaries {
        framework {
            embedBitcode("bitcode")
        }
    }
}

According to other threads, I can check if a framework has bitcode using the following:

$ otool -l libName.o | grep __LLVM

which yelds:

  segname __LLVM
   segname __LLVM

That should mean there's bitcode inside.

Does anybody have an idea why Xcode fails to detect bitcode inside the framework?

Found the answer. Kotlin Multiplatform creates release and debug versions of your targets. The debug version only has bitcode markers while the release version has full bitcode embedded. And I was trying to archive with the debug version of the framework. If I use the release version for archiving, no errors are thrown. The otool method only shows if there are markers which are there in both cases.
