what is the specific technical limitation that prevents multiple MPP frameworks in an iOS app?

There's a runtime assertion that fires when you load the 2 frameworks about not allowing 2 K/N runtimes to run

thank you!

i think at the moment, it has more to do with the vision and less about technical limits, but now that everything is designed this way, it may take work to get out of that world, if JB is so inclined

it definitely adds a lot of overhead for organizations that want to invest in Kotlin MPP

we're working around it by using "export" thing here: https://kotlinlang.org/docs/reference/building-mpp-with-gradle.html

There is overhead for sure, but I wouldn’t say a lot. I have my common code broken out into subprojects and have a buildscript in their root to combine them into a single MPP project: https://github.com/pardom/lambda-news/blob/master/common/build.gradle.kts

a buildscript is definitely helpful

Generally, we suggest modularisation on klib level and single framework at the end

will have to find the best practice for doing so
