在iOS應用運行時期間獲取NSInternalInconsistencyException

將代碼庫從Swift 2升級到Swift 3後，我最近將我的應用從Xcode 7遷移到Xcode 8。該應用程序編譯正常，但在運行時我得到以下異常。在iOS應用運行時期間獲取NSInternalInconsistencyException

不知道這裏需要做什麼。

例外：

SwagListViewController.swift

import UIKit

    var swagList = [

    // code removed for brevity 

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
     let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath as IndexPath) as! SwagCell 

     let object = swagList[indexPath.row] 
     cell.titleLabel.text = object.title 
     cell.priceLabel.text = "$" + object.priceString 
     cell.swagImage.image = object.image 
     return cell 
    } 

    func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
     if segue.identifier == "showDetail" { 
      let object = swagList[self.tableView.indexPathForSelectedRow!.row] 
     (segue.destination as! BuySwagViewController).swag = object 
     } 
    } 

}

SwagCell.swift

import UIKit 

class SwagCell: UITableViewCell { 
    @IBOutlet weak var titleLabel: UILabel! 
    @IBOutlet weak var priceLabel: UILabel! 
    @IBOutlet weak var swagImage: UIImageView! 
}

「出現錯誤是因爲cellForRowAtIndexPath的簽名是錯誤的。在斯威夫特3這是

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

，使用簡便方法

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

它總是返回一個有效的非可選電池「
