When dismiss child parent VC reloads completely

Question

I have so strange issue. I have parent VC named NewAdCreationViewController it presents modally child VC named CollectionPicturesViewController . In child VC I have link to the parent VC.

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

    if segue.identifier == picturesCollectionVCSegueName {

        let collectionController = (segue.destination as! UINavigationController).viewControllers.first as! CollectionPicturesViewController
        let cell = tableView.cellForRow(at: IndexPath(row: 0, section: 0)) as? PicturesCollectionTableViewCell
        guard cell != nil else{ return }
        collectionController.picturesArray = cell!.itemPictures
        collectionController.parentVC = self // this is link!
    }
}

In child VC I present another VC for picking photos - DKImagePickerController (pod). After picking all my photos appears in collectionView in child VC, and when I tap "Save" I want to pass all that data to parent VC and dismiss child,

    @objc func savePictures(){
    self.parentVC.pictures = self.picturesArray
    self.parentVC.tableView.reloadData()

    self.dismiss(animated: true, completion: nil)
}

but after I dismiss it my parent reloads completely and starts from viewDidLoad . It presents completely new VC(I've checked in console, it has another address in memory). I really don't know why is that?

Answer 1

On highlighted segue I've changed presentation to Over full screen . And it works perfectly without reloads!
