TabView in SwiftUI

Using Tabbed Navigation

Open the starter project for this lesson. You’ll recognize it as the project from lesson two changed back to a two-column view. In this lesson, you’ll adapt the list of flights to take advantage of tabs to view different versions of the flight list quickly.

Programmatically Tracking Tabs

When the user leaves and exits the new tabbed view, the app will always start back on the Arrivals tab. Remembering the last viewed tab would be a good interface change. To implement that, in FlightStatusBoard.swift, below the hidePast state variable, add the following line:

@AppStorage("FlightStatusCurrentTab") var selectedTab = 1
