Fixing alignment issues with native popup view controllers

ViewController.swift

import UIKit 

class ViewController: UIViewController {
  
  // Some other code...
  
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
  // The next 3 lines of code will apply the fix IF a view controller is being presented as a popup, to align it to the center of the anchor object's view
        if let popoverPresentationController = segue.destination.popoverPresentationController, let sourceView = sender as? UIView {
            popoverPresentationController.sourceRect = sourceView.bounds;
        }
}
  
}
