SearchField (.searchable) doesn't work with NavigationSplitView

[gojosh]

Description

I have tested SearchField with NavigationSplitView in the simplest possible test case. It works with NavigationStack, but no matter where you put the SearchField introspect, it won't work with NavigationSplitView.

Expected behavior

This should print the statement: "Introspect working"

struct ContentView: View {

    @State var text = ""

    var body: some View {
        NavigationSplitView {
            VStack {
                Text("Hello, world!")
            }
            .searchable(text: $text)
        } detail: {
            Text("Detail View")
        }
        .introspect(.searchField, on: .iOS(.v15, .v16, .v17)) { searchField in
            print("Introspect working")
        }
    }
}

Actual behavior

Nothing is printed, no access to the searchField.

I solved the issue by creating an alternate SearchField with .from(UISplitViewController.self).

extension iOSViewVersion<SearchFieldSplitViewType, UISearchBar> {
    @available(*, unavailable, message: ".searchable isn't available on iOS 13")
    public static let v13 = Self.unavailable()
    @available(*, unavailable, message: ".searchable isn't available on iOS 14")
    public static let v14 = Self.unavailable()
    public static let v15 = Self(for: .v15, selector: selector)
    public static let v16 = Self(for: .v16, selector: selector)
    public static let v17 = Self(for: .v17, selector: selector)

    private static var selector: IntrospectionSelector<UISearchBar> {
        .from(UISplitViewController.self) {
            $0.viewIfLoaded?.allDescendants.lazy.compactMap { $0 as? UISearchBar }.first
        }
    }
}
