tableView.reloadData in folder.didSet conflicts with tableView.deleteRows or tableView.insertRows, so the app will crash on creating or deleting folders.
Two solutions:
Only one update strategy. Delete tableView.deleteRows and tableView.insertRows, or call tableView.reloadData() imperatively instead of auto call in folder.didSet.
Add a condition to tableView.reloadData() in folder.didSet. For example, add a updatingInteractive instance variable, set to true on start of deleteItem(item:) and insert(item:) methods, set to false on end.
