Access Sub-Controllers from a UINavigationController in Swift

This article provides code snippets for iOS developers to access the first child view controller of a UINavigationController in Swift, covering both AppDelegate and prepareForSegue scenarios. It explains how to navigate the view controller hierarchy to set properties on the perceived 'first' view controller when a navigation controller is the root, including a note about iOS 13 SceneDelegate changes. The guide is practical for Swift developers working with navigation controllers in iOS apps.
