Multitasking issues

With app opened in split view, I cannot drag UITableView list items to the other window (if it's the home screen) and drop them to open a new window, like I can with my iPad multitasking app. When I test an iPad device in the 27.1 simulator, selecting New Window from the simulator crashes the simulator. (FB24876909) (I can open in split view from home screen icon, but I can't get any gestures to make the app go from full screen to split view, what is the gesture there?)
