Hide and show navigation bar for specific view without laggy animation

Is there a way to show navigation view on one view and not show it on another at the same time?

The problem: I have two view controllers - table and description view (called on cell click).

Table got a navigation bar, while description view - don't have it.

Table view:

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    self.navigationController?.isNavigationBarHidden = false
}

Description view controller: 

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    self.navigationController?.isNavigationBarHidden = true
}

Everything works fine, but when i swipe for half screen back to table (keeping finger on screen, watching both views) - i don't see navigation bar (which works as expected with that code), and when i release finger - whole table view jumps, because nav bar is shown.

Is there a way to keep not seeing nav bar in description view and see it all the time in table view?

You can hide the navigation bar while doing the segue (earlier). If you're doing it programmatically:

yourVCToBePushed.navigationController?.isNavigationBarHidden = true

If you're doing it in the storyboard, do similarly inside prepareForSegue:

let yourVCToBePushed = segue.destination as! YourVCToBePushed (type)
   yourVCToBePushed.navigationController?.isNavigationBarHidden = true

You can also create your own "navigationView" inside tableView header, and add buttons there.
