swift - SwiftUI list empty state view/modifier

Question

I was wondering how to provide an empty state view in a list when the data source of the list is empty. Below is an example, where I have to wrap it in an if/else statement. Is there a better alternative for this, or is there a way to create a modifier on a List that'll make this possible i.e. List.emptyView(Text("No data available...")).

import SwiftUI

struct EmptyListExample: View {

    var objects: [Int]

    var body: some View {
        VStack {
            if objects.isEmpty {
                Text("Oops, loos like there's no data...")
            } else {
                List(objects, id: .self) { obj in
                    Text("(obj)")
                }
            }
        }
    }

}

struct EmptyListExample_Previews: PreviewProvider {

    static var previews: some View {
        EmptyListExample(objects: [])
    }

}

One of the solutions is to use a @ViewBuilder:

struct EmptyListExample: View {
    var objects: [Int]

    var body: some View {
        listView
    }

    @ViewBuilder
    var listView: some View {
        if objects.isEmpty {
            emptyListView
        } else {
            objectsListView
        }
    }

    var emptyListView: some View {
        Text("Oops, loos like there's no data...")
    }

    var objectsListView: some View {
        List(objects, id: .self) { obj in
            Text("(obj)")
        }
    }
}
