How to display multiple properties from an object in a tableview cell to detail view controller using prepare for segue

Hi I am trying to display a name and a fact about an object in a detail view controller after a user pushes on the tableview cell. Grateful for any help I can get.

I think that it can have something to do with the controller.detailItem

I have the following arrays containing the object information:

let letters = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K, "L", "M"]

let numbers = ["1","2","3","4","5","6","7","8","9","10","11","12", "13"]

Prepare for segue metod:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "showDetail" {

        if let indexPath = self.tableView.indexPathForSelectedRow {
            let letters = letters[indexPath.row] 
            let controller = (segue.destination as! UINavigationController).topViewController as! DetailViewController
            controller.detailItem = letters as AnyObject?

            controller.navigationItem.leftBarButtonItem = self.splitViewController?.displayModeButtonItem
            controller.navigationItem.leftItemsSupplementBackButton = true
        }

        if let indexPath = self.tableView.indexPathForSelectedRow {
            let numbers = numbers[indexPath.row]
            let controller = (segue.destination as! UINavigationController).topViewController as! DetailViewController
            controller.detailItem = numbers as AnyObject?

                controller.navigationItem.leftBarButtonItem = self.splitViewController?.displayModeButtonItem
            controller.navigationItem.leftItemsSupplementBackButton = true
        }
    }
}

DetailViewController.swift:

@IBOutlet weak var letterLabel: UILabel!

@IBOutlet weak var numberLabel: UILabel!

ConfigureView method:

func configureView() { // Update the user interface for the detail item. if let letter = self.detailItem { if let label = self.letterLabel { label.text = letter.description

        }
    }
     if let number = self.detailItem {
     if let label = self.numberLabel {
     label.text = number.description
     }
     }

}
