Answer 1

Swift 4 version

if let viewController = navigationController?.viewControllers.first(where: {$0 is YourViewController}) {
      navigationController?.popToViewController(viewController, animated: false)
}

You may specify another filter on .viewControllers.first as per your need e.g lets say if you have same kind of view controllers residing in the navigation controller then you may specify an additional check like below

  if let viewController = navigationController?.viewControllers.first(where: {
        if let current = $0 as? YourViewController {
             return current.someProperty == "SOME VALUE"
        }
       return false } ) {
            navigationController?.popToViewController(viewController, animated: false)
   }
