Hi, we have a dependency problem with our iOS target

[ribesg]

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

[gonzooin]

[ribesg]

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

[Dico]

I think this would be better asked in #kotlin-native

[svyatoslav.scherbina]

Will be fixed in 1.3.30

[ribesg]

@svyatoslav.scherbina is it fixed in the latest eap?

[svyatoslav.scherbina]

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

[ribesg]

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

[ribesg]

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

[svyatoslav.scherbina]

The compilation error from this screenshot is fixed in 1.3.30.

[ribesg]

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

[svyatoslav.scherbina]

Do you have an issue number we can follow?

What do you mean?

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*.

[ribesg]

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

[ribesg]

@svyatoslav.scherbina I can’t find any docs on how to prevent exporting something referenced by a library I export

[svyatoslav.scherbina]

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

[ribesg]

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

[ribesg]

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

[ribesg]

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

[ribesg]

@svyatoslav.scherbina so what should we do?

[svyatoslav.scherbina]

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.

[ribesg]

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

[ribesg]

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

[svyatoslav.scherbina]

Please inspect your header instead of projects.

[ribesg]

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

[ribesg]

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