Hi folks! I’m having a hard time setting up kotlin-mpp dependencies with ktor and kotlin-serialization. Is there a good example avaialable?

Android works fine but getting following error for iOS

I have a sample with Kotlin/Native: https://github.com/rodolphocouto/swapi-cli

What versions of everything are you using? That error indicates a mismatch between library version and language version.

[Chetan Sachdeva]

Thanks @christophsturm and @rodolpho.couto! @russhwolf I’m using following versions (same as kotlin-conf app):

kotlin_version=1.3.70

# kotlin libraries
coroutines_version=1.3.1
ktor_version=1.3.0-beta-2
serialization_version=0.12.0

# android
gradle_android_version=3.5.0

[russhwolf]

Yeah all your library versions are too old for 1.3.7x. Use coroutines 1.3.5 or 1.3.6, ktor 1.3.2, and serialization 0.20.0.

[Chetan Sachdeva]

Great! I’ll try that. Thanks 🙂

Upgrading everything including gradle build version worked! Thanks everyone! 🙏
