Swift pass data through navigation controller

Override prepareForSegue and set whatever value on the tableview you'd like. You can grab the tableview from the UINavigation viewControllers property.

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!){   let navVC = segue.destinationViewController as UINavigationController   let tableVC = navVC.viewControllers.first as YourTableViewControllerClass   tableVC.yourTableViewArray = localArrayValue   }

For Swift 3 :

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {   let navVC = segue.destination as? UINavigationController   let tableVC = navVC?.viewControllers.first as! YourTableViewControllerClass   tableVC.yourTableViewArray = localArrayValue   }

@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 navigationoverride 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             }        }    }}

SWIFT 3 (tested solution) - Passing data between VC - Segue with NavigationController

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {        let navigationContoller = segue.destination as! UINavigationController        let receiverViewController = navigationContoller?.topViewController as ReceiverViewController        receiverViewController.reveivedObject = sentObject     }
