Swift - 'Pushing a navigation controller is not supported'

I'm trying to push a viewcontroller from a tableviewcell using this code: 

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let vc = storyboard?.instantiateViewController(withIdentifier: "UserPostedViewController") as! UserPostedViewController
    self.navigationController?.pushViewController(vc, animated: true)
}

It's then giving me this error message: 'Pushing a navigation controller is not supported'

I'm also using a XIB file to present the cell. Can anyone help me? Thanks.

use this way

let vc = self.UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "viewController.storyboard.id") as! viewControllerFileName 

self.navigationController?.pushViewController(vc, animated: true)

If you already have a navigation controller, then why are you trying to push to another navigation controller? Just remove the navigation controller and push to it's root view controller should work. Else if you want you can present the navigation controller from current VC.

You are trying to achieve this:

NavigationController -> SomeVC -> AnotherVC -> NavigationController -> NewVC

Try to do it like this:

NavigationController -> SomeVC -> AnotherVC -> NewVC

OR

NavigationController -> SomeVC -> AnotherVC 
                                    | 
                                    | Present
                                    V
                                 NavigationController -> NewVC

UINavigationController can't be pushed, they are presented with presentViewController:animated

If you wish to retain the push animation remove the navigation controller from your UserPostedViewController.
