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

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

 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
