help you fix your problem I have an application with the option to change a users password. The reset password process is all done via web links. When the process is complete, the user returns to their app. Given that the password has now been changed, i would like to log the user out. , Make sure you have to run the UI events on main thread.
code :
DispatchQueue.main.async {
    let loginVC = self.storyboard?.instantiateViewController(withIdentifier: "login") as! MyLoginViewController
    self.present(loginVC, animated: true, completion: nil)

How to access one UIViewControllers properties from another UIViewController?

With these it helps It doesn't make sense to push a new ViewController from the SecondaryViewController in the MainViewController. This screws up the design of the code. A child object will access its parents method to call a method. By other words: bad code. Make a delegate call from the SecondaryViewController to the MainViewController that it state has changed. Then the MainViewController can decide to do with the call and the SecondaryViewController will not know anything about the implementation of the MainViewController.
So: Make a protocol in SecondaryViewController. Let the MainViewController be SecondaryViewController's delegate. Implement the delegate method in MainViewController which pushes the new ViewController.

hope this fix your issue In prepareForSegue: call self.navigationController.popViewControllerAnimated(true) before segueing and it will release the current view controller from the stack before pushing the next one on.

UIViewController containing a flow of UIViewControllers

it fixes the issue Heavily inspired by @7vikram7 I ended up with a container view that embedded a UINavigationController which had my InnerViewController as its root viewController:
In my InnerViewController I am now able to push to any UIViewController, and control my navigation stack, for example:
code :
override func viewDidLoad() {

    // Hide the navigation bar
    self.navigationController?.setNavigationBarHidden(true, animated: false)

    // Push to whatever viewController I want to
    let viewController = self.storyboard?.instantiateViewControllerWithIdentifier("myAwesomeViewController") as! AwesomeViewController
    self.navigationController?.pushViewController(viewController, animated: true)

should help you out How do I check if two UIViewController subclassed objects have the same subclass? , In Swift 3 you can compare object's types with type(of:) method:
code :
class VC1: UIViewController {


class VC2: UIViewController {


let vc1 = VC1()
let vc2 = VC2()

let typeComparisonResult = type(of: vc1) == type(of: vc2)

I hope this helps . Yes, it is permitted, moreover, a very common method to use segues this way. They can ease visualizing navigation between view controllers and help structuring the project.
