Answer 1

You can use popToViewController:

Basic setup:

let nav = UINavigationController()
let vc1 = UIViewController()
vc1.title = "vc1"
let vc2 = UIViewController()
vc2.title = "vc2"
let vc3 = UIViewController()
vc3.title = "vc3"
let vc4 = UIViewController()
vc4.title = "vc4"
nav.viewControllers = [vc1,vc2,vc3,vc4]

Then pop to vc2 (which is at index 1 in the array):

let vcs = nav.viewControllers
nav.popToViewController(vcs[1], animated: true)
//OR, if you still have a reference to the view controller
nav.popToViewController(vc2, animated: true)
