What:

Knowledge base:

• https://kotlinlang.org/docs/multiplatform-build-native-binaries.html#export-dependencies-to-binaries "For example, you implement several modules in Kotlin and want to access them from Swift. Usage of several Kotlin/Native frameworks in a Swift application is limited, but you can create an umbrella framework and export all these modules to it."
