Conflict resolution for FileDocument?

Using the new SwiftUI support for FileDocument, is there a way to provide conflict resolution like there is for UIDocument? UIDocument provides documentState and stateChangedNotification. There is nothing defined in the FileDocument that indicates this capability. And SwiftUI does not seem to provide any automatic conflict resolution UI for your app. So when the user selects a document with conflicting versions, your app is unaware and simply opens the document for the user to edit.
Please support this feature, otherwise we won't be able to use the SwiftUI's FileDocument in a production app!!!
