> One more nitpick: the use of View Modifiers on children noticed by parents (like the `navigationBarTitle` example he uses (as discussed in the "Child Privacy Invasion" section), is to allow for children to specify metadata that the parent might care about. This is actually pretty nice, because then you can nicely compose together the various parts of your app without having to spread around the configuration for your tab bars and such (which is a bit messy in UIKit). I wouldn't say it's too messy in UIKit but I agree with the motivation. To add some more context here's how you configure the title of the navigation bar in UIKit navigationItem.title = "My Title" navigationItem.largeTitleDisplayMode = .always This does not happen in the class that renders the navigation bar(UINavigationController) nor does it happen in the navigation bar view itself(UINavigationBar) it happens in the view controller that is currently on screen and is the "active" child of UINavigationController.
