Hi, we have a dependency problem with our iOS target

The headers of the Framework produced by the MPP iOS App Project are invalid, they contain duplicated information

The MPP iOS App Project `export`s both projects A and B. Projects Y, A and B have `kotlinx.serialization` and `ktor` as dependencies.

I think this would be better asked in <#C3SGXARS6|kotlin-native> 

<@U3SRWNXQB> is it fixed in the latest eap?

Yes.
Btw, why do you find headers containing duplicated information?

Well that’s the whole issue, and you just said it’s fixed, so I don’t understand your question

XCode refuses to compile stating that the framework is invalid, and shows what <@U97KSKDHD> screenshoted above when opening the header file of the Framework.

The compilation error from this screenshot is fixed in 1.3.30.

Ok, thanks for the confirmation. We’ll start migration to 1.3.30 EAP then. Do you have an issue number we can follow?

&gt; Do you have an issue number we can follow?

What do you mean?

&gt; We’ll start migration to 1.3.30 EAP then

Alternatively you can prevent exporting `JsonPrimitive` to framework headers and continue using 1.3.2*.

I mean that this issue should have been reported somewhere like on <https://youtrack.jetbrains.net/> but I can’t find it

<@U3SRWNXQB> I can’t find any docs on how to prevent exporting something referenced by a library I export

Do you export `kotlinx.serialization` explicitly, like you do with project `A`?

We never explicitely export `kotlinx.serialization`, `ktor-client` or any other lib

We only `export` Projects X, A and B in the MPP iOS App Project, we don’t export any other lib. Just 3 `export` calls

We have `kotlinx.serialization` as a dependency of a lot of project but it’s never exported using the `export` function as the MPP iOS App Project is the only one creating a Framework

If you don’t use `transitiveExport` in Gradle, then `JsonPrimitive` class is exported because it is used in public API. Please inspect your header to locate public API which brings `JsonPrimitive` to the header.

<@U3SRWNXQB> we’re exposing a `val` of type `KotlinxSerializer.() -&gt; Unit` in an `object`. Would that cause `JsonPrimitive` to be exported somehow? It’s the only thing we found

There is no direct reference to `JsonPrimitive` in any of those project, public or not

Please inspect your header instead of projects.

Ok, we found it. We have a reference to `Json` is a public API, which references `JsonElement`, which references `JsonPrimitive`

We will need this reference in the future but not right now, so I guess it’ll have to wait for 1.3.30
