Custom View Controller not appearing

Report

Trying to add a custom ViewController to add a TextField is not working as expected. I followed this example but the "RATE THIS APP" is showing on top of the buttons and isn't showing the TextField at all.

let viewController = JoinViewController(nibName: "JoinViewController", bundle: nil)
            
            let popup = PopupDialog(viewController: viewController, 
buttonAlignment: .horizontal, 
transitionStyle: .bounceDown, 
tapGestureDismissal: true, 
panGestureDismissal: false)
            
            popup.addButton(DefaultButton(title: "Join Random", action: nil))
            popup.addButton(CancelButton(title: "Cancel", action: nil))
            self.present(popup, animated: true, completion: nil)
