viewDidLoad() is called every time after dismiss() of UIImagePickerController()

I presented UIImagePickerController() from ViewControllerA and when I select a image its delegate called and in that delegate I wrote 

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

        dismiss(animated: true, completion: nil)
}

but viewDidLoad() of ViewControllerA also called

Please find below code, viewDidLoad doesn't get called every time.

override func viewDidLoad() {
    super.viewDidLoad()
    print("View Did Load")
}

private func imagePickerController(_ picker: UIImagePickerController,
                           didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    picker.dismiss(animated: true, completion: nil);

    _ = info[UIImagePickerControllerOriginalImage] as! UIImage
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    picker.dismiss(animated: true, completion: nil)
}

Open Photo Library using this code,

@IBAction func btnclicked(_ sender: Any) {
    let picker = UIImagePickerController()
    picker.sourceType = .photoLibrary
    picker.delegate = self
    self.present(picker, animated: true, completion: nil)
}

Also post some of your code so I can review it.

Let me know in case of any queries.

When using the UIImagePickerViewController, often times the camera will cause a memory warning and your viewcontroller's viewDidUnload method will be called. Next time your view is shown (when the UIImagePickerViewController is dismissed), the viewDidLoad method will be called because it was previously unloaded.
