Question

I am using kotlin multiplatform v1 5 10 to build binaries for Android and iOS I have 2 kotlin native project a core and a client In the core project I have a singleton using kotlin object with threadlocal annotation which is find in the client The problem is at the client export to Apple Framework via cocoapods plugin v1 5 10 this singleton present in core seems not being exported and is not reachable through xcode The module is well exported and other class are visible I guess it s because the singleton is kind of declared as unused Do you know how I could tell cocoapods plug in to keep this singleton or to not remove unused code Many thks

mbonnin · Answer

I d expect singletons to be exported even if unused <https kotlinlang org docs native objc interop html kotlin singletons>

Nicolas Demoisson · Answer

Well if I directly import my core project the singleton is imported But not if I import the client wich import the core project in its dependencies with api

mbonnin · Answer

Ah

mbonnin · Answer

That rings a bell I ve done things like this before ``` macosX64 binaries framework export project core ```

Nicolas Demoisson · Answer

I have tried this but the cocoapods plugin has already generated these binaries Gradle throw an error like binaries already exist

Nicolas Demoisson · Answer

Ps it works normally when I use the client in an Android project

mbonnin · Answer

Maybe something like ``` macosX64 binaries get project name as org jetbrains kotlin gradle plugin mpp Framework export project core ```

mbonnin · Answer

To configure an already existing binary

mbonnin · Answer

not exactly sure about what name the binary is registered under but you can print them and try to guess or read the Kotlin plugin source

Nicolas Demoisson · Answer

This end to sync error I ve tried ```binaries getFramework DEBUG export com myLib core Core 1 0 0 getFramework RELEASE export com myLib core Core 1 0 0 ``` this does not throw error but it s not working either

Nicolas Demoisson · Answer

Without it my core code is imported only the singleton is not

Nicolas Demoisson · Answer

Seems like only my interfaces are exported

You might also need to add `transitiveExport = true` to pick up declarations in the platform specific sources and not just in common

Nicolas Demoisson · Answer

Adding export myLibrary + transitiveExport made it work Thank you both
