Answer 1

let storyboard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    let popupVC = storyboard.instantiateViewController(withIdentifier: "WSFilterViewController")
    popupVC.modalPresentationStyle = UIModalPresentationStyle .popover
    popupVC.preferredContentSize = CGSize(width: 170, height: 130)
    popupVC.popoverPresentationController?.delegate = self
    popupVC.popoverPresentationController?.sourceView = sender as? UIView // button
    popupVC.popoverPresentationController?.sourceRect = (sender as AnyObject).bounds
    self.present(popupVC, animated: true, completion: nil)

The issue was something different and figured it out now.

Thanks everyone

 func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle
{
    return .none
}

you must add the code above on iPhone devices, otherwise it will keep showing full screen.
