UIImage not passing from one ViewController to other

I am trying to pass the image which is captured from UIImagePickerController to another ViewController but the image is not getting passed.

This is the code of the first ViewController:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])
{
    chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage 
    newImageView.contentMode = .scaleAspectFit 
    newImageView.image = chosenImage 

    self.performSegue(withIdentifier: "pass", sender: self)

    dismiss(animated:true, completion: nil) 

    let svc = self.storyboard!.instantiateViewController(withIdentifier: "demoViewController") as! demoViewController
   present(svc, animated: true, completion: nil)

}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "pass"
    {
        let imgpass = segue.destination as! demoViewController
        imgpass.newphoto = chosenImage
    }
}

Code for the second ViewController:

override func viewDidLoad() {
    super.viewDidLoad()

    myImageView.image = newphoto
}

I went through a lot of other similar postings and implemented them too but couldn't get the image passed.

Try this

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])
    {
        if let chosenImage = info[UIImagePickerControllerOriginalImage] as? UIImage {

        newImageView.contentMode = .scaleAspectFit
        newImageView.image = chosenImage

        picker.dismiss(animated: true, completion: nil)

        let svc = self.storyboard!.instantiateViewController(withIdentifier: "demoViewController") as! demoViewController
        svc.newphoto = chosenImage
        self.present(svc, animated: true, completion: nil)
    }
}

The problem is that your func prepare(for:sender:) implementation is never called, so your newphoto is never set. prepare(for:sender:) is sent before a segue. But there is no segue. You are presenting in code, not with a segue.
