How can I push the next view controller on a navigation controller programmatically?

Question

How can I push the next view controller on a navigation controller programmatically (without the need of a button)?

I know how to instantiate and present a new controller is the below

 var next = self.storyboard?.instantiateViewControllerWithIdentifier("PlaceInfo") as! PlaceInfoController         
 self.presentViewController(next, animated: false, completion: nil)

but I want to push to the next view controller on the navigation controller. I tried the below self.navigationController?.pushViewController() but no success

 var next = self.storyboard?.instantiateViewControllerWithIdentifier("PlaceInfo") as! PlaceInfoController
 self.navigationController?.pushViewController(next, animated: true)

Have you tried using performSegueWithIdentifier ?
