Answer 1

No need to use a new navigation bar just use your existent navigation bar. Remember what you did here :

let nc1 = UINavigationController(rootViewController: vc1)

So your view controller is already embed inside a navigation controller just use self to access to the navigation items

self.title = "Your Title"

var homeButton = UIBarButtonItem(title: "LeftButton", style: .Plain, target: self, action: "")

var logButton = UIBarButtonItem(title: "RigthButton", style: .Plain, target: self, action: "")

self.navigationItem.leftBarButtonItem = homeButton
self.navigationItem.rightBarButtonItem = logButton
