Hello @Hartmut Neubauer ,
After discussing with the team, the only supporting Frameworks available are Android & .Net 6. Therefore, it cannot work for iOS at this time. It can work for Xamarin Android in a single project. And there is no built-in support for Kotlin in iOS.
Only a single LibraryProjectZip can be included in a Xamarin.Android binding project. This limitation will be removed in .NET 6. See : Build Items - Xamarin | Microsoft Learn.
(1) create and compile a Kotlin Multiplatform Mobile (KMM) project in Android Studio
For the Android Studio issue, you can send the feedback to them, see: Feedback - Android Studio Project Site
(2) import the business code into iOS with XCode to create a native library or framework, (until here it works)
This needs to be discussed with Apple, you can create a new thread on Apple forums and get help from Apple at https://developer.apple.com/forums/
(3) bind this with MS VS into a Xamarin project (maybe Xam Forms).
It's recommend to submit feed back through the VS2022 Feedback channel, be sure to provide detailed information of what you want to achieve. About how to report the feedback to the product team, see : Report a problem with Visual Studio - Visual Studio (Windows) | Microsoft Learn
