Dagger for Android and a manual service locator for iOS

means shared code has no notion of DI, only the implementing app?

Yes, yet the ios service locator is based in the iosMain module and the dagger module is implemented in main android app

How is that working for you? I'm toying with that idea. However often "module owner" knows best how to scope dependencies for a given module, and it kind of makes sense to have di module definitions in a given module, but it also limits reusability if you want to say change scope ..so..im not sure
