thank you for contacting us. Indeed the case you have presented is somewhat complex. In general, the iOS tableview (which is the basis of our listview widget) responds and navigates to taps and swipes. We can reduce the responsiveness to tap only, allowing for the drawer to handle the swipe, but in that case this will reduce the listview usability.
Given that, I can't provide a definitive answer about how this case should be handled. In case you have any insight (or examples), please share them.
