swift - firestore cannot delete cells in tableview without error

I have been reading and researching and trying to implement different tactics of deleting a cell in the UITableview with Firestore as well and I just keep seem to get the same error.

Here is the error and i'll add my function down below.

Error

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath, for orientation: SwipeActionsOrientation) -> [SwipeAction]? {
    guard orientation == .right else { return nil }

let deleteAction = SwipeAction(style: .destructive, title: "Delete") { action, indexPath in
      
        

    
    DispatchQueue.main.async {
        self.documentsID.remove(at: indexPath.row)
        tableView.deleteRows(at: [indexPath], with: .fade)
          
        self.events.count - 1
        
            
        self.tableView.reloadData()
    }
        
        self.db.document("school_users/(self.user?.uid)/events/(self.documentsID[indexPath.row]!.docID)").delete { (error) in
            if let error = error {
                print("There was an error trying to delete the documents: (error)")
            } else {
                print("Successfully deleted the documents.")
                

            }


        }
    
    
       
                       
    }



   
    deleteAction.image = UIImage(named: "delete-icon")

    return [deleteAction]
}

Here is my function, I've altered it about 20 times and still get the same result, some posts say to delete from tableview first, some say delete from Firestore first and I've tried both ways and still fail. If anybody can just correct me real quick that would be great. Thanks.
