I Use trailingSwipeActionsConfigurationForRowAt in IOS11 but when swipe multiple then app cracked.

You need to implement tableView(_:editActionsForRowAt:).
As a minumum, return empty array, but not nil:
nil
override func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? { return [] }
