Swift线程1信号SIGABRT错误

Question

我正在制作一个简单的hi应用程序。但是当我运行应用程序时遇到了问题。它什么也没显示，在调试屏幕中它会显示这个0xcf49c＆lt; + 140＆gt;：xorl％ecx ，％ecx线程1：信号SIGABRT.Here是我的ViewController.swift文件

import UIKit

class ViewController: UIViewController {

@IBOutlet var Label: UILabel!
@IBOutlet var NameField: UITextField!
@IBAction func SayMyName(sender: UIButton) {
  let nameEntered = NameField.text
  Label.text = "Hi there \(nameEntered)"

}
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.
    }


   }

这是我的联系
