I need to send some data back from secondView to First View by popView. How can i send back the data by popViewControllerAnimated?

Extending Dheeraj's answer in case your ViewController is not first VC in the stack, here is the solution:

func popViewController() {
  guard let myVC = self.navigationController?.viewControllers.first({ $0 is MyViewController }) else { return } 
  myVC.data = "data"
  self.navigationController?.popViewController(animated: true)
}

However, this solution will break if you have 2 or more than 2 MyViewController in the stack. So, use wisely.
