Полная ошибка:

Мой код:

import UIKit

class CameraViewController: UIViewController {

@IBOutlet weak var captionTextView: UITextView!
@IBOutlet weak var photo: UIImageView!
@IBOutlet weak var shareButton: UIButton!
var selectedImage: UIImage?
override func viewDidLoad() {
    super.viewDidLoad()

    let tapGesturn = UITapGestureRecognizer(target: self, action: #selector(self.handleSelectPhoto))
    photo.addGestureRecognizer(tapGesturn)
    photo.isUserInteractionEnabled = true

}

@objc func handleSelectPhoto() {
    let pickerController = UIImagePickerController()
    pickerController.delegate = self
    present(pickerController, animated: true, completion: nil)
}

@IBAction func shareButton_TouchUpInside(_ sender: Any) {

}
}
 extension CameraViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
private func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    print("did Finish Picking Media")
    if let image = info["UIImagePickerControllerOriginalImage"] as? UIImage{
        selectedImage = image
        photo.image = image
    }
    dismiss(animated: true, completion: nil)
  }
}
