BarButtonItem not appearing

I have a simple + button on the right side to add rows to my tableView, however the button is not appearing. This is how i implement it

let AddButton = UIButton()
AddButton.setTitle("+", forState: .Normal)
let AddView = UIBarButtonItem(customView: AddButton)
self.navigationItem.rightBarButtonItem = AddView
AddButton.addTarget(self, action: #selector(self.addRow), forControlEvents: UIControlEvents.TouchUpInside)


Note, I use the same exact implementation for my hamburger button which does appear. This is the working hamburger button implementation

let navicon = UIButton(type: UIButtonType.System)
navicon.setImage(defaultMenuImage(), forState: UIControlState.Normal)
navicon.frame = CGRectMake(0, 0, 30, 30)
let menu = UIBarButtonItem(customView: navicon)
self.navigationItem.leftBarButtonItem = menu
self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
navicon.addTarget(self.revealViewController(), action: #selector(SWRevealViewController.revealToggle(_:)), forControlEvents: .TouchUpInside)


why is this happening?

Answer

Try:

let AddButton = UIButton(type: .Custom)
AddButton.frame = CGRectMake(0, 0, 44, 44)
