찍거나 이미지 갤러리에서 선택한 이미지 불러오기 코드

extension ViewController : UIImagePickerControllerDelegate,
UINavigationControllerDelegate {
    
    //사진 찍은 후, 앨범에서 사진을 가져온 후 실행되는 함수
           @available(iOS 2.0, *)
           public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]){
               
            
            if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
            {
                dragImageView.image = image
                for a in info {
                    print(a)
                }
               //print(info)
                
            }

//                print("captureImage: \(String(describing: captureImage))")

//                       UIImageWriteToSavedPhotosAlbum(captureImage, self, nil, nil)
//                   }
//
//                   //imageView.image = captureImage
//               }
               self.dismiss(animated: true, completion: nil)
           }

           @available(iOS 2.0, *)
           public func imagePickerControllerDidCancel(_ picker: UIImagePickerController){
               self.dismiss(animated: true, completion: nil)
           }
    
}

dragImagveView는 UIImageView 입니다.
