I'm trying to implement “Save image to Library” function and then return back to the current view controller, but on a new iOS 13 it dismisses back to the view controller that presented the current one:

PHPhotoLibrary.requestAuthorization({(_ status: PHAuthorizationStatus) -> Void in })

let shareItems: Array = [newImg,"Hello"] as [Any]

let activityController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)

if UIDevice.current.userInterfaceIdiom == .pad {
    activityController.popoverPresentationController?.sourceView = saveButton
}

present(activityController, animated: true)
