Is there any convenient way to back deploy the NavigationStack or NavigationSplitView??

The real problem is if I want to back support iOS 15 or 14, I must conditionally switch between NavigationView and NavigationStack / NavigationSplitView.

Here is how I did for NavigationStack, but I have no idea how to deal with NavigationSplitView

import SwiftUI

struct NavigationStack<Content: View>: View {
    var content: () -> Content

    var body: some View {
        if #available(iOS 16.0, macOS 13.0, *) {
            SwiftUI.NavigationStack {
                content()
            }
        } else {
            NavigationView {
                content()
            }.navigationViewStyle(.stack)
        }
    }
}

Will the new NavigationStack and NavigationSplitView back support old devices? I think these behaviors in previous OS is not new features.

NavigationView has only been soft deprecated, so will still function on iOS 16. As for manually back deploying, since NavigationView has been split into two parts but come with added components, such as a path and control over column visibility as well as the new NavigationLink(_:value:) and navigationDestination modifier, it would be quite difficult to accomodate all of this.
