kotlinlang

Hi all, I'm new to Kotlin. Do you know is it possible to create cross-platform library that uses some shared library, e.g. `.so` in kotlin for Android and iOS?

iOS doesn't use the `.so` format (<https://stackoverflow.com/a/13616064|more information>), this is unrelated to Kotlin.

Regarding Kotlin: yes, you can create a project which uses native libraries, using Kotlin/Native (<#C3SGXARS6|kotlin-native>). Note that is considered "single platform" in Kotlin-speak ("multiplatform" would mean using Kotlin/Android on Android, running on ART, and Kotlin/Native on iOS).

The linked SO answer seems to say dynamic libraries are forbidden by the App Store, but I don't know enough to confirm or deny.

Thanks a lot, I've access to the source I that library, so I should cross-compile the library once for android and once for iOS and the use kotlin-native to use that library on each platform, am I right?

Yes. You can read more <https://kotlinlang.org/docs/native-overview.html|here>, and ask your questions in <#C3SGXARS6|kotlin-native>.

On iOS, the library should create a dylib. You can use kotlin's cinterop to call into it.
