Selected Tab Binding

Track and change the active tab in code.

Knowing the Active Tab

Sometimes your code needs to know or change which tab is showing. For that you bind the selection to your own state. 🎯

First mark each tab with a unique tag value so SwiftUI can identify which one is selected.

HomeScreen()
    .tabItem { Label("Home", systemImage: "house") }
    .tag(0)
