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

I was getting this error to Horatio's solution.

ERROR: Value of type 'UINavigationController' has no member 'yourTableViewArray'

So this might help others like me looking for a code only solution. I wanted to redirect to a Navigation controller, yet pass data to root view controller within that Nav Controller.

if let controller = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "yourNavigationControllerID") as? UINavigationController,
   let yourViewController = controller.viewControllers.first as? YourViewController {
        yourViewController.yourVariableName = "value"
        self.window?.rootViewController = controller  // if presented from AppDelegate
        // present(controller, animated: true, completion: nil) // if presented from ViewController
}

Answer 2

FIXED syntax 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
    }
