Here\'s what I want:

I\'ve tried creating my own UIBarButtonItem

Answer 1

Note: Please remember that the back button belongs to the the source ViewController and not to the destination ViewController. Thus, the modification needs to be done in the source VC, which is reflected to all the view in the navigation controller

Code Snippet:

let backImage = UIImage(named: "icon-back")

self.navigationController?.navigationBar.backIndicatorImage = backImage

self.navigationController?.navigationBar.backIndicatorTransitionMaskImage = backImage

/*** If needed Assign Title Here ***/
self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.plain, target: nil, action: nil)
