I am attempting to use swift export, with a module that uses Ktor. I am getting an error because some code has a member called 'description'. Tried the latest Kotlin 2.4.0-Beta2 and the same issue. Is there a way to define the module in gradle so that Ktor is not even exposed to the iOS side. I have everything wrapped in a way that the iOS side should not need anything from Ktor. Thanks!

Hi, I guess you let everyhing public in your module ? try to use explicitApi() Gradle rule to control the visibility of your code

it’s just a rule to explicitly expose your code to the consumer

Are you using api(…ktor) or implementation(…ktor) in your Gradle file?

<https://docs.gradle.org/current/userguide/java_library_plugin.html#sec:java_library_recognizing_dependencies|https://docs.gradle.org/current/userguide/java_library_plugin.html#sec:java_library_recognizing_dependencies> 

implementation in commonMain for all ktor modules, and implementation for darwin in iosMain

Everything public in your imported module is exposed to iOS

FYI <https://youtrack.jetbrains.com/issue/KT-85869/Swift-Export-release-function-conflicts-with-unavailable-NSObject.release|https://youtrack.jetbrains.com/issue/KT-85869/Swift-Export-release-function-conflicts-with-unavailable-NSObject.release>

Found some of my issue. I have multiple modules, one depending on the other, and one exposes koin or Ktor types, which then cause all of that to be exported. And I cannot make them internal or they are not visible cross module. So perhaps one large module with tighter control on internal and public is a better way to go?

Hello there, thanks for the report :slightly_smiling_face:

As Rick mentioned already - this(the original report) is a known problem that was fixed already in 2.4.20 dev builds.

This is also a known request, please follow <https://youtrack.jetbrains.com/issue/KT-85687> :slightly_smiling_face:

These part of DSL have no impact on the export feature of kotlin compiler - neither Objective-C export nor Swift Export relies on those.

Does `@HiddenFromObjectiveC` solves your current problem?

Okay the @HiddenFromObjC was the key I was missing to clean up the exported Object-C header. Now I will try the Swift Export again.
