If I understand correctly, in KMP we need the libraries to use the same Kotlin version as the app.
I'm currently using kotlin version 1.3.71 which gives me an error trying to pack for xcode :
w: skipping /Users/[myusername]/.gradle/caches/modules-2/files-2.1/org.reduxkotlin/presenter-middleware-iossim/0.2.10/6b469d298fb83098e67e4112f7a1259f31fa75ae/lib.klib. The abi versions don't match. Expected '[22]', found '9'
Looking at the presenter-middleware code it seems to be using 1.3.41 which is where the problem possibly comes from?
