Answer 1

Kodunuz Tamam görünüyor, ancak Xcode 9'da hücrelerin silinmesiyle ilgili bir hata oluştu. Kodunuzu Xcode 8'de denerseniz, muhtemelen işe yarayacaktır. Daha fazla bilgi için this numaralı telefonu arayınız.

Örneğimi kullanmaya çalışıyorum.

class ViewController: UIViewController { 

    @IBOutlet weak var tableView: UITableView! 

    var data = ["Byba", "Boba", "Gent", "Xpa", "zc", "123", "swipe", "gen", "sw", "xcas", "kjs", "908"] 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 
    } 

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


} 

// MARK: - UITableViewDelegate 
extension ViewController: UITableViewDelegate { 

    func tableView(_ tableView: UITableView, titleForDeleteConfirmationButtonForRowAt indexPath: IndexPath) -> String? { 
     return "delete" 
    } 

    func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool { 
     return true 
    } 

    func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) { 
     if editingStyle == .delete { 
      tableView.beginUpdates() 
      data.remove(at: indexPath.row) 
      tableView.deleteRows(at: [indexPath], with: .left) 
      tableView.endUpdates() 
     } 
    } 
} 

// MARK: - UITableViewDataSource 
extension ViewController: UITableViewDataSource { 

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
     return data.count 
    } 

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
     let cell = UITableViewCell() 
     let item = data[indexPath.row] 

     cell.textLabel?.text = item 

     return cell 
    } 
}
