Back Button not visible for custom navigation item added to UIViewController

Question

Displaying an UIViewController modally from one of the View Controllers(which are in a Navigation controller) code :

self.present(viewController, animated: true, completion: nil)

Within the modal ViewController, a custom Navigation Bar along with navigation item is added. In which, i'm trying to display the Back Button.

let backButton = UIBarButtonItem()
backButton.title = "Back"
self.navigItem.backBarButtonItem = backButton  //self.navigItem is the custom Navigation Item

Is there something im missing here?

thanks in advance, Rajesh

present VC does not embed with Navigationcontroller, if you need embed your VC in nav controller and present your VC, else progrmatically create navigation bar in presented VC — Anbu.Karthik, Aug 31 '17 at 11:24
VC needs to be presented modally not added in the nav controller, Have added the custom Navigation Bar in the StoryBoard for this viewcontroller. Im able to add/show other bar button items except back button. — Rajesh Rs, Aug 31 '17 at 11:27

Im able to add the left button item as Back, can i access the system back icon to set or i need to add as part of the image assets and access? — Rajesh Rs, Aug 31 '17 at 11:38
Added a Left "Back" Bar Button Item to the Navigation Bar, Now trying to add Back icon to image assets so that i can set it to the button. — Rajesh Rs, Aug 31 '17 at 11:48
if you want to handle the back button action use custom else no need — Anbu.Karthik, Aug 31 '17 at 11:49

 let btnleft : UIButton = UIButton(frame: CGRect(x:0, y:0, width:35, 
                           height:35))
 btnleft.contentMode = .center
 btnleft.setImage(Set_Local_Image("arrow_left"), for: .normal)
 btnleft.addTarget(self, action: #selector(YOUR_ACTION), for: .touchDown)

 let backBarButon: UIBarButtonItem = UIBarButtonItem(customView: btnleft)
 self.navigationItem.setLeftBarButtonItems([menuBarButon], animated:false)

In Swift3 try this code on the viewDidLoad

    self.navigationController?.navigationBar.backIndicatorImage = UIImage(named: "arrow_left")
    self.navigationController?.navigationBar.backIndicatorTransitionMaskImage = UIImage(named: "arrow_left")
    UIBarButtonItem.appearance().setBackButtonTitlePositionAdjustment(UIOffsetMake(0, -60), for:UIBarMetrics.default)
    self.navigationController?.navigationBar.tintColor = UIColor.white
    self.navigationItem.hidesBackButton = false
