import UIKit

class PopoverMenuController: UITableViewController {
    static let MENU_CELL_HEIGHT = 45
    var menuOptions: [MenuOption]?
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        self.view.alpha = 0
        self.popoverPresentationController?.containerView?.alpha = 0
    }
    
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        UIView.animate(withDuration: 0.2, delay: 0.0, options: .beginFromCurrentState, animations: {
            self.view.alpha = 1
            self.popoverPresentationController?.containerView?.alpha = 1
        }, completion: nil)
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    // MARK: - Table view data source

    override func numberOfSections(in tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        return 1
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // #warning Incomplete implementation, return the number of rows
        return menuOptions!.count
    }
    
    override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return CGFloat(PopoverMenuController.MENU_CELL_HEIGHT)
    }
    
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "popoverMenuCell", for: indexPath) as! PopoverMenuCell
        cell.title.text = menuOptions![indexPath.row].title.localized
        cell.img.image = menuOptions![indexPath.row].image


        return cell
    }
    
    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        menuOptions![indexPath.row].action()
        self.dismiss(animated: false, completion: nil)
    }

}

PopoverMenuCell.swift

//
//  PopoverMenuCell.swift
//

import UIKit

class PopoverMenuCell: UITableViewCell {

    @IBOutlet weak var title: UILabel!
    @IBOutlet weak var img: UIImageView!
    
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }

}

showPopoverMenu.swift

class PopoverUtils {
  static func showPopoverMenu(_ sourceViewController: UIViewController, source: UIView, presentationDelegate: UIPopoverPresentationControllerDelegate, menuOptions: [MenuOption]) {
        let vc = UIStoryboard(name: "Popover", bundle: Bundle.main).instantiateViewController(withIdentifier: "popoverMenuController") as! PopoverMenuController
        vc.menuOptions = menuOptions
        vc.modalPresentationStyle = .popover
        vc.preferredContentSize = CGSize(width: 175, height: PopoverMenuController.MENU_CELL_HEIGHT * menuOptions.count)
        
        if let presentationController = vc.popoverPresentationController {
            presentationController.delegate = presentationDelegate
            presentationController.backgroundColor = UIColor(hex: 0xEAEAEA)
            presentationController.permittedArrowDirections = UIScreen.main.bounds.height -  (source.superview?.convert(source.frame.origin, to: nil).y)! < 150 ? .down : .up
            presentationController.sourceView = source
            presentationController.sourceRect = source.bounds
            sourceViewController.present(vc, animated: true, completion: {
                vc.view.superview?.layer.cornerRadius = 0
            })
        }
    }
}

You also need to create a Storyboard with the PopoverMenuController viewCtlr in it - name it "popoverMenuController".
You can also create it as a .xib file..

Example of how to use:

let menuOptions = [
	MenuOption(title: "menu_item_edit_basket".localized,   image: #imageLiteral(resourceName: "ico-edit-basket"), action: { self.editBasket(basket) }),
	MenuOption(title: "menu_item_delete_basket".localized, image: #imageLiteral(resourceName: "ico-delete-basket"), action: { self.deleteSavedBasket(basket) })
]

        
PopoverUtils.showPopoverMenu(self, source: sender, presentationDelegate: self, menuOptions: menuOptions)
