'Xcode fails to build KMM project due to shared:linkPodDebugFrameworkIos
I am building a small project with KMM, it builds perfectly fine on android but cannot build it in XCode. Cocoapods was also installed an genereted without any erros.
What I'm using:
- macbook air m1
- Kotlin 1.6.10,
- gradle 7.3.0-alpha03
- Ktor 1.5.2,
- SQLDelight 1.4.3,
You can find the project here: https://github.com/PiotrKedra/comperative-analysis-of-kmm-flutter-react-native/tree/master/preapp-kmm
The error I got:

For Kotlin 1.6.10, you need Ktor that was build on Kotlin 1.6.10. Ktor 1.6.8 is what you need. You will also need to inclode Kotlinx.serialization into the common module. Currently, you only have the plugin for Ktor (I'm guessing you are trying to deserialize network calls directly into appropriate data classes).
