31.3 Adding the Data Structure

The first step before a list can be displayed is to add the data structure that will form the basis of the user interface. Each row within the list will be represented by an instance of a structure named CarInfo designed to store the following information:

import SwiftUI

 

struct CarInfo: Identifiable {
