iPhone - how to put Settings bundle seen through System Settings App into your own App?

Question

I want to create a settings page from within my app that looks exactly like the one that I would create in the System Settings Application using a Settings.bundle and Root.p

On iOS 8 and later, if you already have a settings bundle, it's dead easy to launch from your app into the Settings app to manage it: (Swift 3 example)

if let settingsURL = URL(string: UIApplicationOpenSettingsURLString) {
            UIApplication.shared.open(settingsURL)
        }
