Working with Navigation View

Just build something that you'd want to use today, not something you think people would use somehow.

– Paul Graham

First things first, what is a navigation view? Similar to list views, navigation views are commonly used UI components in iOS apps. They offer a drill-down interface for presenting hierarchical content. Take a look at the pre-installed Photos app, YouTube, and Contacts. All of them utilize navigation views to display content in a hierarchical manner. Typically, you combine a navigation view with a stack of list views to create a sophisticated interface for your apps. However, it's important to note that you are not obligated to use both together. Navigation views can be employed alongside any type of view.

Creating Navigation Views

Let's head back to the FoodPin project and open the RestaurantListView.swift file.

Hold the control key and click List in RestaurantListView. In the context menu, choose Embed.... Then change the default Container to NavigationStack. In iOS, you use NavigationStack to create a navigation view.
