If you’ve designed a view that you know will be presented as part of a navigation stack, but doesn’t itself contain a navigation stack, you won’t see its navigation title or buttons by default.
Fortunately, you can add your view to a navigation stack right inside your preview – this simulates having a navigation bar at the top without actually adding one for the live code, so you can see exactly how it looks.
For example, this view has no navigation stack but is configured to display in a specific way when presented as part of one – i.e. being pushed from another view:
struct ContentView: View {
var body: some View {
Text("Hello World")
.navigationTitle("Welcome")
}
}
To preview that in a navigation stack, just add a NavigationStack
around the content view in your preview, like this:
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
NavigationStack {
ContentView()
}
}
}
This allows you to see accurately how the view will look without having to modify the view’s actual layout.
