How to hide and show the status bar

We can hide and show the iOS status bar using SwiftUI’s statusBar() modifier. This takes one hidden parameter that must be either true or false, depending the behavior you want:

Text("No status bar, please")
    .statusBar(hidden: true)

Important: This modifier is available only on iOS.

If you want status bar visibility to be dependent on some program state, use an @State Boolean in place of a hard-coded value. For example, this creates a hideStatusBar Boolean that gets toggled when a button is tapped, which in turn controls whether the status bar is showing or not:

struct ContentView: View {
    @State private var hideStatusBar = false

    var body: some View {
        Button("Toggle Status Bar") {
            withAnimation {
                hideStatusBar.toggle()
            }
        }
        .statusBar(hidden: hideStatusBar)
    }
}

As you can see, that toggles the Boolean inside a withAnimation block, which causes the status bar to fade in and out smoothly.
