Easiest way is to use UINavigationController: From A -> B (this code in A):

navigationController?.pushViewController(ViewControllerB(), animated: true)

From B -> C (this code in B):

navigationController?.pushViewController(ViewControllerC(), animated: true)

From C -> A (this code in C):

navigatinoController?.popToRootViewController(animated: true)

If you're using a UINavigationController you can use popToRootViewController

import UIKit

class AViewController: UIViewController {}
class BViewController: UIViewController {}
class CViewController: UIViewController {}

let a = AViewController()
let b = BViewController()
let c = CViewController()

let nav = UINavigationController(rootViewController: a)
nav.pushViewController(b, animated: true)
nav.pushViewController(c, animated: true)

// Option 1
nav.popToRootViewController(animated: true)

// Option 2
nav.popToViewController(a, animated: true)
