popoverController not seguing - swift

Question

Hi I have a popover view that is showing an array. I am wondering if there is a way that I could somehow segue back which item's in the array are selected.
#IBAction func popOverButton(_ sender: UIButton)
{
let controller = TableViewController()
//This is just a regular tableViewController nothing special
controller.modalPresentationStyle = .popover
// configure the Popover presentation controller
let popController: UIPopoverPresentationController? = controller.popoverPresentationController
popController?.permittedArrowDirections = [.down]
popController?.delegate = self
popController?.sourceView = sender
popController?.sourceRect = sender.bounds
popController?.backgroundColor = .white
self.parent?.present(controller, animated: true, completion: { })
}
Here is what it looks like
Any help is appreciated thanks

Easiest way is to create a delegate and when a cell is selected pass the selection back to the presenting view controller. Then setting up the UITableViewDelegate method didSelectRowAtIndexPath to call the delegate method. Something like this:
#protocol PopoverOptionSelectionDelegate {
func itemSelected(item:String);
}
Implement the method in your presenting VC
class PresnetingViewController, PopoverOptionSelectionDelegate {
#IBAction func popOverButton(_ sender: UIButton) {
let controller = TableViewController()
controller.delegate = self //----Important---//
//This is just a regular tableViewController nothing special
controller.modalPresentationStyle = .popover
// configure the Popover presentation controller
let popController: UIPopoverPresentationController? =
controller.popoverPresentationController
popController?.permittedArrowDirections = [.down]
popController?.delegate = self
popController?.sourceView = sender
popController?.sourceRect = sender.bounds
popController?.backgroundColor = .white
self.parent?.present(controller, animated: true, completion: { })
}
func itemSelected(item:String) {
//DISMISS YOUR POPOVER MAYBE AND DO SOMETHING WITH "ITEM" HERE
}
}
class TableViewController,UITableViewDelegate {
weak var delegate:PopoverOptionSelectionDelegate?
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
delegate?.itemSelected(self.itemsArray[indexPath.row])
}
}
