如何从 Firebase 单击 TableViewCell - SWIFT 获取当前子项（AutoID）？

Question

我需要通过单击 TableViewCell 从 Firebase 获取当前子项（AutoID）。 我有带有名称的单元格，我需要从当前名称（单元格）获取 ID 并传递到另一个视图 controller ，其中将显示该人的更多详细信息。 所以，我是 swift 的新手，我想知道如何获取 ID？ 这是在我的 VC1 ->

'''

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let selectedGuest = guestsList[indexPath.row]
        let controller = self.storyboard?.instantiateViewController(identifier: 
  "GuestDetail") as! GuestDetailsViewController
        
        controller.guestUser = selectedGuest
       self.present(controller, animated: true, completion: nil)
    }

//这是我的 VC 2

 func showGuestDetails(){
   ref = Database.database().reference().child("userInfo").child(uid!).child("guests")
        ref.queryOrderedByKey().observeSingleEvent(of: .value) { (snapshot) in
            if snapshot.childrenCount>0{
                self.guestDetail.removeAll()

                for guests in snapshot.children.allObjects as![DataSnapshot]{
                    let guestObject = guests.value as? [String: AnyObject]
                    let name = guestObject?["guestName"]
                    let familyName = guestObject?["guestFamilyName"]
                    let phone = guestObject?["guestPhoneNumber"]
                    guard let email = guestObject?["guestEmail"] as? String,
                        email != self.guestUser?.guestEmail else {
                        continue
                    }

                    let guest = GuestModel(guestName: name as? String, guestFamilyName: familyName as! String, guestPhoneNumber: phone as? String, guestEmail: email as? String)
                    self.phoneNoLabel.text = guest.guestPhoneNumber
                    self.emailLabel.text = guest.guestEmail
                }
            }
        }
        self.nameLabel.text = guestUser!.guestName
    }
