SwiftUI Control Flow and ViewBuilder

Question

I want to have a mother view that displays a different child view based on a @State bool. However I get two errors when doing that.

On the start of the body closure:

Struct 'ViewBuilder' requires that 'EmptyCommands' conform to 'View'

Return type of property 'body' requires that 'EmptyCommands' conform to 'View'

And inside the control flow statement:

Closure containing control flow statement cannot be used with result builder 'CommandsBuilder'

struct ResultView: View {
    @State var resultViewSuccess = false

    let resultViewModel: ResultViewModel

    var body: some View {
        Group {
            if let showresultView = resultViewSuccess {
                ViewOne(viewModel: resultViewModel)
            } else {
                ViewTwo(
                    resultViewSuccess: $resultViewSuccess,
                    viewModel: resultViewModel,
                )
            }
        }
    }
}

struct ViewTwo: View {
    @Binding var resultViewSuccess: Bool
    @StateObject var viewModel: ResultViewModel

    var body: some View {
        NavigationView {
            ButtonResult(
                resultViewSuccess:       $resultViewSuccess, 
                viewModel: viewModel)
        }               
    }


struct ButtonResult: View {
    @Binding var resultViewSuccess: Bool
    @StateObject var viewModel: ResultViewModel

    var body: some View {
        Button(action: {
            self.resultViewSuccess = true
        }) {
            Text("View Results")
        }
    }
}
