Hello everyone, can anyone explain why do we need to add library separately in androidMain and iosMain and then commonMain, can't we add at once in commonMain and use it for ios and android both

I think since kotlin 1.4 you only have to add libraries to common main if it is a multiplatform library.

i was going though https://github.com/kotlin-hands-on/kmm-networking-and-data-storage kotlin hands for kmm they added ktor and sqldelight library in all platform like in commonMain, androidMain and in iosMain also

Nope that is not what is happening

okay then same way for ios also right

I think it counts for the other platform specific implementations as well

thanks @Joost Klitsie

You are welcome, it is not as straightforward as they make it sound :)
