You could try this

struct ListRows: View {
    let title: String
    let type: String

    var body: some View {
        HStack {
            Text(title)
                .font(.headline)

            Spacer()

            Text(type)
                .font(.headline)
                .foregroundColor(.secondary)
        }
    }
}

Then could put that into your List

struct ContentView: View {
    var body: some View {
        NavigationView {
            List {
                ListRows(title: "Name", type: "Nigel's iPhone  12")
                ListRows(title: "Software Version", type: "15.3.1")
                ListRows(title: "Model Name", type: "iPhone 12 Pro Max")
            }
            .listStyle(.grouped)
            .navigationTitle("About")
            .navigationBarTitleDisplayMode(.inline)
        }
    }
}
