I have got the problem after upgrade of xcode to 15+ from 14.3
My app worked fine. But last time i edited it in Oct 2023.
Then my mac had been upgraded to new macos and xcode also upgraded to v.15
And compilation of the iOS app stopped to work.

I have found recommendations to upgrade Gradle and Kotlin. I have done this. Gradle upgraded from 7.5 to 8.2 and Kotlin from 1.6.* to 1.9.24
Android app is compiled fine. But iOS has a problem.

There is the error. kmmsharedmodule is the name of my shared module

Any idea what to do with this?
I can not find same error on the web. I have done usual basic things like “clean project”, reset gradle cache etc.
