If your loginViewcontroller is rootviewcontrollerand and you have only oneNavigation controller` to reach particular view then in that particular view you can write on logout button's click,

   self.navigationController?.popToRootViewControllerAnimated(true)

If you have two NavigationController between to reach that view then,

 self.navigationController?.navigationController?.popToRootViewControllerAnimated(true)

Likewise you can handle multiple navcontroller also.

Assuming the very first view in your navigation controller is the login view controller, you can do: navigationController!.popToRootViewControllerAnimated(false)

If your Login controller is root controller then you can move like this

self.navigationController?.popToRootViewControllerAnimated(true)

else

//Move to login view
let viewControllers = self.navigationController?.viewControllers as NSArray!
for vc in viewControllers {
    if vc.isKindOfClass(LoginViewController.classForCoder()) {
        self.navigationController?.popToViewController(vc as! UIViewController, animated: false)
        break
    }
}
