Hi! I'm trying to add a dependency to our MPP project and have everything public from that dependency exported as obj-c classes in that framework. we tried the export thing in binaries.framework, but that doesn't seem to work. Anyone else have success with this?

as far as I know that's not a supported use case. but perhaps someone from JB can chime in with an official answer.

If I understand correctly, the export you're using is for creating a framework from your Kotlin/Native code which you can then call into from a Swift/Obj-C project. What you probably want is cinterop to be able to access an existing framework from Kotlin

[Kris Wong]

I just reread the docs on the export keyword and I am mistaken. that's exactly it's use case. how is the dependency your using specified in your build.gradle?

[Sam]

Is your dependency a binary framework or a klib? Export should work for klibs and not for binary frameworks. In macOS and iOS frameworks aren't technically supposed to depend on another framework though in practice that doesn't happen. Your iOS app should directly include any binary frameworks that your Kotlin framework depends on and it should be listed in the embedded binaries and linked frameworks sections of your target's general tab in Xcode. If you're using Cocoapods declare the same dependencies in your Podfile.

i can confirm i have taken these steps for an obj-c framework dependency declared via cinterop

[Kris Wong]

however, it seems that a dependency that can be declared via api in the build.gradle can be exported

[Kris Wong]

i haven't tried that

we're trying to do export 'com.somegroup.project:project:version'

[basher]

that style of export should work, right?

[basher]

(it's a klib)

Issue was the note at the bottom here about gradle metadata: https://github.com/ilmat192/kotlin-native-gradle-samples/blob/master/export-kotlin-multiplatform/framework/build.gradle.kts

By specifying the build variant, it worked!
