ios - NSInternalInconsistencyException，在我关闭下一个场景后崩溃

Question

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (1) must be equal to the number of rows contained in that section before the update (10), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).'

我的应用程序在此页面崩溃

import UIKit
import MapKit
import CoreLocation

struct place {



}



class CourseClass: UITableViewController, CLLocationManagerDelegate, MKMapViewDelegate {


    @IBOutlet weak var map: MKMapView!



    var place = ["Caffè Spagar", "Duks", "Posta station", "Barnum", "Elephant Club", "Cinema", "Space", "Andromeda", "Rodolf", "Devil Chair"]
    var rows = 0





    override func viewDidLoad() {
        super.viewDidLoad()

      map.showsUserLocation = true
      map.delegate = self
    }



    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)

        insertRowsMode3()
    }


    func insertRowsMode2() {

        for i in 0..<place.count {
            insertRowMode2(ind: i, str: place[i])
        }

    }

    func insertRowMode2(ind:Int,str:String) {

        let indPath = IndexPath(row: ind, section: 0)

        rows = ind + 1
        tableView.insertRows(at: [indPath], with: .right)
    }



   func insertRowsMode3() {

        rows = 0

        insertRowMode3(ind: 0)
    }




  func insertRowMode3(ind:Int) {
        let indPath = IndexPath(row: ind, section: 0)
        rows = ind + 1
        tableView.insertRows(at: [indPath], with: .right)


        guard ind < place.count-1 else { return }
        DispatchQueue.main.asyncAfter(deadline: .now()+0.15) {

            self.insertRowMode3(ind: ind+1)
        }
    }











    override func numberOfSections(in tableView: UITableView) -> Int {

        return 1
    }


    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        return rows
    }



    public override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

      let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! MyTableViewCell

        cell.myImage.image = UIImage(named: (place[indexPath.row] + ".png"))
        cell.myLabel.text = place[indexPath.row]

        return (cell)
    }





    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

       performSegue(withIdentifier: "goToLast" , sender: place[indexPath.row])

    }


    override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 100
    }





    @IBAction func mapTapped(_ sender: Any) {

    let userLocation = map.userLocation

    let region = MKCoordinateRegionMakeWithDistance((userLocation.location?.coordinate)!,2000,2000)

    map.setRegion(region, animated: true)
    }







    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "goToLast" {

        guard let vc = segue.destination as? FinalClass else { return }

        let guest = segue.destination as! FinalClass

        guest.local = sender as! String

        guest.localImage = UIImage(named: (sender as! String) + ".png")!

        }
    }


override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

在我关闭下一个 UIViewController 后；所以当我从上一个场景进入页面时，这是可以的，但是如果我之后继续进入场景，然后返回

 @IBAction func lastBack(_ sender: Any) {

    dismiss(animated: true, completion: nil)
    }

应用程序崩溃了，我该怎么办？
