我的准备Segue()方法不起作用

Question

所以我正在尝试将图像从第一页移动到第二页。但是我的 prepare(( 方法不起作用，我不知道为什么..我试图在准备函数之前放置覆盖，但它说该函数没有覆盖任何东西，所以我不能。

import UIKit
class BeginningPage: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate  {
@IBOutlet weak var ImageView: UIImageView!
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    // Dismiss the picker if the user canceled.
    dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    // The info dictionary may contain multiple representations of the image. You want to use the original.
    guard let selectedImage = info[UIImagePickerControllerOriginalImage] as? UIImage else {
        fatalError("Expected a dictionary containing an image, but was provided the following: (info)")
    }
    // Set photoImageView to display the selected image.
    ImageView.image = selectedImage
    // Dismiss the picker.
    dismiss(animated: true, completion: nil)
}
//MARK: Action
@IBAction func PressImage(_ sender: UITapGestureRecognizer) {
    let imagePickerController = UIImagePickerController()
    imagePickerController.sourceType = .photoLibrary
    imagePickerController.delegate = self
    present(imagePickerController, animated: true, completion: nil)
}
func prepare(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "mySegue" {
    if let destination = segue.destination as? ViewController {
        destination.text = "123"
        destination.image = ImageView.image
        destination.LayerImage.image = ImageView.image
         }
      }
   }
}

你的命名是错误的。在文档中检查正确的版本。方法定义应如下所示：

斯威夫特 3：

override func prepare(for segue: UIStoryboardSegue, sender: Any?)

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?)
