How to dismiss and pop to viewcontroller simultaneously

My home viewcontroller is Tabbarcontroller

So, I want to first dismiss presented viewcontroller and then I want to pop my previous pushed controller

Here is my navigation flow 

From Tabbarviewcontroller 
1-  let aVC = self.storyboard?.instantiateViewController(withIdentifier: "a") as! OrderListingViewController
     self.navigationController?.pushViewController(aVC, animated: true)

From A viewcontroller 
2- let bVC = self.storyboard?.instantiateViewController(withIdentifier: "b") as! OrderListingViewController
     self.navigationController?.pushViewController(bVC, animated: true)

From B viewcontroller 
        let cVC = self.storyboard?.instantiateViewController(withIdentifier: "c") as! RejectOrderViewController
        cVC.providesPresentationContextTransitionStyle = true
        cVC.definesPresentationContext = true
        cVC.modalPresentationStyle=UIModalPresentationStyle.overCurrentContext
        self.tabBarController?.presentVC(cVC)

so from C Viewcontroller when i dismiss i want to show Tabbarviewcontroller or (A) ViewController

I had to use NotificationCenter to pop the previous controller.

let back_view = Notification.Name("back_view")

//Here's the action to close the actual controller

 @IBAction func closeWW(_ sender: Any) {
                
        self.dismiss(animated: true, completion: {
            NotificationCenter.default.post(name: self.back_view, object: nil)
        })
    }

//Now, in the previous controller

override func viewDidLoad() {
NotificationCenter.default.addObserver(self, selector: #selector(popView), name: back_view, object: nil)
}

@objc func popView(){
    self.navigationController?.popViewController(animated: true)
}

Maybe it's not the best answer, but it's work for me :)

When you present any model at that time form this model to not working pop view controller because this is presented model

for that you can use presented model parent Object Just like below

let presentViewController = self.storyboard?.instantiateViewControllerWithIdentifier("PresentVC") as! PresentVC
presentViewController.parentModel = self
self.presentViewController(presentViewController, animated: true, completion: nil)

and dismiss view controller like this

self.dismissViewControllerAnimated(true) { 

           for controller in self.navigationController!.viewControllers as Array {
                if controller.isKind(of: ViewControllers) {
                     parentModel.navigationController!.popToViewController(controller, animated: true)
                     break
                }
           }
      }

and in block pop to your controller

You could do like below.

    // First, finding specific Navigation Controller and do pop.
    if let tabBarController = presentingViewController as?  UITabBarController {
        if let navigationController = tabBarController.viewControllers?[0] as? UINavigationController {
            navigationController.popToRootViewController(animated: false)
            // Then, dismiss self.
            self.dismiss(animated: true, completion: nil)
        }
    }

You have to dismiss the ViewController C in the following way.

self.presentingViewController will give the previous view controller object.

Move to Root view controller 

  let presentingVC = self.presentingViewController
  self.dismiss(animated: true) { 
      presentingVC?.navigationController?.popToRootViewController(animated: false)
  }

Move to previous controller

If you need to previous view controller instead of root view controller then you have to just to a popViewController

let presentingVC = self.presentingViewController
 self.dismiss(animated: true) {
      presentingVC?.navigationController?.popViewController(animated: false)
 }

Move to a specific View Controller

    let presentingVC = self.presentingViewController
    self.dismiss(animated: true) {
            if let  destinationVC =  presentingVC?.navigationController?.viewControllers.filter({$0 is <Your Destination Class>}).first {
                presentingVC?.navigationController?.popToViewController(destinationVC, animated: false)
            }
        }

<Your Destination Class> replace with your destination class name.

TRY BELOW CODE

self.navigationController?.dismiss(animated: true, completion: {
     for controller in self.navigationController!.viewControllers as Array {
          if controller.isKind(of: BVC) {
               self.navigationController!.popToViewController(controller, animated: true)
               break
          }
    }

})

In ViewController B, you can write below code.

self.navigationController?.dismiss(animated: true, completion: {
     self.navigationController?.popToRootViewController(animated: true)
})
