Getting following error when building iOS shared module with molecule dependency ```e Module app cash molecule molecule runtime app cash molecule molecule runtime iosarm64 has a reference to symbol androidx compose runtime Composition setContent| 2259719813581705387 0 Neither the module itself nor its dependencies contain such declaration ``` What am I doing wrong I am using Kotlin 1 8 0

```This could happen if the required dependency is missing in the project Or if there is a dependency of app cash molecule molecule runtime app cash molecule molecule runtime iosarm64 that has a different version in the project than the version that app cash molecule molecule runtime app cash molecule molecule runtime iosarm64 0 7 0 was initially compiled with Please check that the project configuration is correct and has consistent versions of all required dependencies The list of app cash molecule molecule runtime app cash molecule molecule runtime iosarm64 0 7 0 dependencies that may lead to conflicts 1 stdlib 1 8 0 was initially compiled with stdlib 1 6 21 2 org jetbrains kotlin native platform CoreFoundation 1 8 0 was initially compiled with org jetbrains kotlin native platform CoreFoundation 1 6 21 3 org jetbrains kotlin native platform darwin 1 8 0 was initially compiled with org jetbrains kotlin native platform darwin 1 6 21 4 org jetbrains kotlin native platform posix 1 8 0 was initially compiled with org jetbrains kotlin native platform posix 1 6 21 5 org jetbrains kotlinx atomicfu org jetbrains kotlinx atomicfu iosarm64 0 18 5 was initially compiled with org jetbrains kotlinx atomicfu org jetbrains kotlinx atomicfu iosarm64 0 17 3 6 org jetbrains kotlinx kotlinx coroutines core org jetbrains kotlinx kotlinx coroutines core iosarm64 1 6 4 was initially compiled with org jetbrains kotlinx kotlinx coroutines core org jetbrains kotlinx kotlinx coroutines core iosarm64 1 6 1 ```

Do you have <https github com cashapp molecule blob trunk gradle properties L37 L39|https github com cashapp molecule blob trunk gradle properties L37 L39> in your project

Nope will try thank you

Filip Wiesner · Answer

Thank you that definitely helped But now I see this error not sure if it s related ``` gt Task sharedMobile linkDebugFrameworkIosArm64 FAILED e Applications Xcode app Contents Developer Toolchains XcodeDefault xctoolchain usr bin ld invocation reported errors The Applications Xcode app Contents Developer Toolchains XcodeDefault xctoolchain usr bin ld command returned non zero exit code 1 output Undefined symbols for architecture arm64 kfun path to Composable function referenced from more objc2kotlin kfun stuff ld symbol s not found for architecture arm64``` But at least I have different error now after an hour of debugging smile

saket · Answer

are your composable functions public

Filip Wiesner · Answer

yes

saket · Answer

what happens if you make them internal

kevin.cianfarini · Answer

If its the above its a bug in the compose compiler in I think IOS source sets

Filip Wiesner · Answer

huh that works thinking face So the workaround is to expose only the `StateFlow` and keep the ` Comcposable` functions internal I guess confused

Filip Wiesner · Answer

Thank you Saket You saved me a few hours of debugging relieved

kevin.cianfarini · Answer

We currently just have an abstract class that declares our molecule stuff as internal Will move to an interface with a public function when thats resolved

Pablichjenkov · Answer

For more information on the Composable internal issue Notice the problem is only in the last module that builds the iOS target You can have libraries that expose them as public <https github com JetBrains compose jb issues 2346|https github com JetBrains compose jb issues 2346>
