    die top-Antwort für swift 3:

     let homeButton = UIButton(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
 homeButton.setBackgroundImage(#imageLiteral(resourceName: "home-1"), for: .normal)
 homeButton.addTarget(self, action: #selector(homePressed), for: .touchUpInside)
 self.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: homeButton)
