Back Button Left Alignment IOS 9

I m trying to left align back button ie remove the space on the left of the back arrow . Using a custom back button .

let backButton = UIBarButtonItem(image: UIImage(named: "arrow03"), style: .Plain, target: self, action: "back")

self.navigationController?.navigationBar.tintColor = UIColor.clearColor()
self.navigationItem.backBarButtonItem = backButton

Tried to use negative width for the button as suggested in the below SO link but it didnt work.

    let barButton = UIBarButtonItem(customView: button)

    self.navigationItem.leftBarButtonItem = barButton
