Answer 1

if you want to create it programmatically u can try this in ur view did load method

let rightBarButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.plain, target: self, action: #selector(ViewController.myRightSideBarButtonItemTapped(_:)))
self.navigationItem.rightBarButtonItem = rightBarButton


let leftBarButton = UIBarButtonItem(title: "Edit", style: UIBarButtonItemStyle.done, target: self, action: #selector(ViewController.myLeftSideBarButtonItemTapped(_:)))
self.navigationItem.leftBarButtonItem = leftBarButton
//Mark - Call functions
func myRightSideBarButtonItemTapped(_ sender:UIBarButtonItem!)
{
    print("myRightSideBarButtonItemTapped")
}

func myLeftSideBarButtonItemTapped(_ sender:UIBarButtonItem!)
{
    print("myLeftSideBarButtonItemTapped")
}
