如何创建共享导航栏以在 SwiftUI 中的多个视图之间进行交互导航？

Question

I would like to navigate among screens A, B, and C by tapping the corresponding button in a shared navigation bar at the bottom of every screen. How can I create such a toolbar to achieve this inter-navigability among screens?

You would use a TabView {...} to accomplish this. Effectively you instantiate your views inside of the TabView then add an item modifier to each view.

var body: some View {
    TabView {
        Text("A")
            .tabItem { Text("A") }
        Text("B")
            .tabItem { Text("B") }
        Text("C")
            .tabItem { Text("C") }
    }
}
