数组索引超出范围 - Swift

Question

我在Swift中创建了一个ToDoList应用程序，它在三天前完美运行但是当我回到计算机时，我收到了此错误消息。致命错误：数组索引超出范围。有人能告诉我如何解决这个问题。

import UIKit

var date = [String]()

var todoItem = [String]()

class SwiftController: UIViewController{


@IBOutlet weak var table: UITableView!
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return date.count
}


func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) ->UITableViewCell{


    let cell = UITableViewCell(style: UITableViewCellStyle.Value1, reuseIdentifier: "cell")




    cell.textLabel!.text = date[indexPath.row]

    cell.detailTextLabel!.text = todoItem[indexPath.row]


    return cell
}


func tableView(tableView:UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath){
    if editingStyle == UITableViewCellEditingStyle.Delete
    {
        todoItem.removeAtIndex(indexPath.row)
        date.removeAtIndex(indexPath.row)


        NSUserDefaults.standardUserDefaults().setObject(todoItem, forKey: "ToDoItem ")


        NSUserDefaults.standardUserDefaults().setObject(date, forKey: "ToDoDate")

        table.reloadData()

    }
}




override func viewDidLoad() {
    super.viewDidLoad()


    if
        NSUserDefaults.standardUserDefaults().objectForKey("date") != nil{

            date = NSUserDefaults.standardUserDefaults().objectForKey("date") as! [String]

    }

    if
        NSUserDefaults.standardUserDefaults().objectForKey("ToDoDate") != nil{

            date = NSUserDefaults.standardUserDefaults().objectForKey("ToDoDate") as! [String]
    }





    // Do any additional setup after loading the view.
}

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

}
