Swift pass data through navigation controller

Question

One of my segues transitions from a view controller to a tableview controller. I want to pass an array between the two, but with a navigation controller before the tableview

Answer 1

@Tommy Devoy's answer is correct but here is the same thing in swift 3

Updated Swift 3

  // MARK: - Navigation

//In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    // Get the new view controller using segue.destinationViewController.
    // Pass the selected object to the new view controller.


    if segue.identifier == "yourSegueIdentifier"  {

        if let navController = segue.destination as? UINavigationController {

            if let chidVC = navController.topViewController as? YourViewController {
                 //TODO: access here chid VC  like childVC.yourTableViewArray = localArrayValue 


            }

        }

    }

}
