Accessing a UIViewController using storyboardID without instantiating it

Is there any way to access a UIViewController without using the function instantiateViewController(withIdentifier: String). I have to call the function tableView.ReloadData() from within another UIViewController which I have transitioned to using a show segue and I therefore do not want to instantiate the initial UIViewController again.

Thanks.

You can access through UINavigationController stack. Let say if it is one controller before, you can access it using the total viewcontrollers (in stack) minus 2

let previousController = self.navigationController?.viewControllers[(self.navigationController?.viewControllers.count)! - 2] as! YourViewController

more simplified

let controllerIndex = (self.navigationController?.viewControllers.count)! - 2
let previousController = self.navigationController?.viewControllers[controllerIndex] as! YourViewController
