I have added a KMM module to my existing Android project via the wizard. The iOS project is in another repository. What's the easiest way for us to make a KMM proof-of-concept in the iOS repository? I would expect a generated ObjectiveC framework from the android project but can't seem to find it...

Well, I would add cocoapods support to the KMM project, then just have both projects’ roots in the same folder. Then you can use a relative path to point at the cocoapods podspec
