Introduction to navigation

Paul Hudson    @twostraws   

Updated for Xcode 14.2

Navigation sits at the heart of so many apps, and SwiftUI does a great job of making it easy out of the box. This means we get a simple and natural approach using NavigationLink, full control over programmatic navigation using Navigationpath, support for two- and three-view layout with NavigationSplitView, and more.

This means a lot of the time you can forget about the easier stuff and focus on the parts that need more thought, such as:

  • Making customizable toolbars with sensible defaults
  • Saving and loading your user’s navigation with state restoration
  • Deciding when and how to show a sidebar, or adding an extra content view if needed.
  • Combining NavigationSplitView and NavigationStack to get exactly the structure you want.

These aren’t necessarily hard, they just take more planning to get right.
