I unwind from controller B to controller A.

When I print my view controllers stack on my unwind function (controller A), I still have my controller B in stack.

Is it normal that after an unwind the controllers stack is not updated ?!

Controller B:

self.bookmarkViewController.performSegue(withIdentifier: "unwindToViewController", sender: nil)

Controller A

@IBAction func unwindToViewController(segue: UIStoryboardSegue) {
print(self.navigationController?.viewControllers)
}

Yes. At the point that unwindToViewController is called, the segue is not yet completed. For this reason, you can't push a new ViewController from this routine or trigger a new segue.

When viewDidAppear runs, the viewControllers stack will have been updated.
