You can make the navigation bar transparent in viewWillAppear and remove transparency in viewWillDisappear as follows

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
    self.navigationController?.navigationBar.shadowImage = UIImage()
    self.navigationController?.navigationBar.isTranslucent = true
}
override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    self.navigationController?.navigationBar.setBackgroundImage(nil, for: .default)
    self.navigationController?.navigationBar.shadowImage = nil
    self.navigationController?.navigationBar.isTranslucent = false
}

The background image and the back button will be visible
