Present Next ViewController to Dismiss current ViewController Using Swift

Question

My Scenario, I have three ViewControllers, those ViewControllers First, Second, Third. Here, First ViewController UIButton click to present model second ViewController and then Second ViewController UIButton click to present model Third ViewController. I need to Implement the Second ViewController button click to dismiss current ViewController after presenting Third ViewController because once I close Third ViewController I need to show First ViewController. How to Achieve this?

NOTE: I am having NavigationController for Third ViewController also I am using Storyboard.

Here's my code:

@IBAction func ClickThirdVC(_ sender: Any) {
    if let VC_Third = self.storyboard?.instantiateViewController(withIdentifier: "thirdviewcontroller") as? ThirdvViewController {
        weak var pvc = self.presentingViewController
        VC_B.modalTransitionStyle = .crossDissolve
        let navController = UINavigationController(rootViewController: VC_B)
        self.dismiss(animated: true, completion: {
            pvc?.present(navController, animated: true, completion: nil)
        })
    }
}

You can try to dismiss self after presenting the third UIViewController, in the completion handler of the present function .

secondVC?.present(navController, animated: true) {
            self.dismiss(animated: false, completion: nil) //dismiss self after presenting the third. 
        }
