    Hi

    To present a controller as a popOver we use UIPopoverPresentationController. It  display the content in a popover. We can easily do it by setting controller presentation Style as popover and then presenting it.

    Add UIPopoverPresentationControllerDelegate on your ViewController

    class ViewController: UIViewController , UIPopoverPresentationControllerDelegate{
    }

    Instantiate a controller from Storyboard  and set its modalPresentationStyle as popOver , we can also manage its arrow direction by setting permittedArrowDirections.

    let popVc = self.storyboard?.instantiateViewController(withIdentifier: "PopOverViewController") as? PopOverViewController 
            
            popVc?.modalPresentationStyle = .popover
            let popover = popVc?.popoverPresentationController!
            popover?.delegate = self      
            popover?.permittedArrowDirections = .down // for arrow direction
            popVc?.preferredContentSize = CGSize(width: 100, height: 100) //set size of popover 
            popover?.sourceView = popVc?.view
            popover?.sourceRect = CGRect.init(x: 150, y: 200, width: 50 , height: 50) // set the  point  to display popover
            present(popVc!, animated: true, completion:nil) // present PopOver

    Once done with the above steps, conform UIPopoverPresentationControllerDelegate method to avoid full screen presentation

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

    To dismiss PopOver add :

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

    Thanks
