How to Push a New View Without Storyboards Swift

Question

First of all, I don't want to use storyboards at all. I am able to "present" the targeted view controller, but I can't get it to show with the standard iOS back button at the top. My understanding is I can get this to work by pushing the controller instead of presenting it. I don't get any errors, but nothing happens.

On a button click this code is run. The commented code is what successfully presented the ForgotPasswordPage :

// Changes to Forgot Password Page

func forgotPasswordSwitch(sender: UIButton!) { 
   //let ForgotPassword:ForgotPasswordPage = ForgotPasswordPage()
   //self.presentViewController(ForgotPassword, animated: true, completion: nil)
    let ForgotPassword = ForgotPasswordPage()
    self.navigationController?.pushViewController(ForgotPassword, animated: true)
}

You have to manually create a UINavigationcontrollerto get the back bar. To do this you can use the code from this answer, which achieves this by using this code:

self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
var nav1 = UINavigationController()
var mainView = ViewController() //ViewController = Name of your controller
nav1.viewControllers = [mainView]
self.window!.rootViewController = nav1
self.window?.makeKeyAndVisible()

Here just add all the ViewControllers you want to be under the Navigation controller into the array and then push between them.

Hope that helps, Julian
