Using gestures with TabView

In the preceding recipe, we learned how to switch between tabs using the navigation pane at the bottom of the screen. However, when building an app, the client may want something else to trigger the navigation. Navigation between TabView tabs can be performed programmatically. In this recipe, we will use a tap gesture to trigger the transition from one tab to another, but the concept can be generalized to any other programmatic trigger.

Getting ready

Create a SwiftUI app for iOS and name it TabViewWithGestures.

How to do it

We will implement a screen with two TabView structs where the user would be able to transition between tabs by using the tab bar at the bottom of the screen or by clicking on some text. The steps are as follows:

1. Click on the ContentView.swift file to open it in the editor window.
2. Add an @State variable that holds the value of the currently selected tab. The variable should be located just above the body variable...
