у меня есть код для выпадающего списка, но из-за большого количества информации список не пролистывается вниз, может вы мне сможете помочь

import UIKit

class TimetableEconomViewController: UIViewController, UIPopoverPresentationControllerDelegate {
  @IBOutlet weak var Econom1: UIButton!
  override func viewDidLoad() {
    super.viewDidLoad()
    setupGestures()
  }

  private func setupGestures() {
    let tapGesture = UITapGestureRecognizer(target: self, action: #selector(tapped))
    tapGesture.numberOfTapsRequired = 1
    Econom1.addGestureRecognizer(tapGesture)
  }

  @objc
  private func tapped(){
    guard let popVC = storyboard?.instantiateViewController(withIdentifier: "popVC" ) else {return}

    popVC.modalPresentationStyle = .popover

    let popOverVC = popVC.popoverPresentationController
    popOverVC?.delegate = self
    popOverVC?.sourceView = self.Econom1
    popOverVC?.sourceRect = CGRect ( x: self.Econom1.bounds.midX, y:self.Econom1.bounds.midY,width: 0, height: 0 )
    popVC.preferredContentSize = CGSize(width:250, height: 250 )

    self.present (popVC, animated: true)
  }
}

extension ViewController: UIPopoverPresentationControllerDelegate {
  func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
    return .none
  }
}

This doesn't look like the code for a drop-down list, just the code for managing an unknown view as a pop-over.

We encourage questions about just using Apple frameworks to be asked at the Apple developer forums.

I have the code for the drop-down list, but because of the amount of information the list doesn't flip down, maybe you can help me.
