32.3 Creating the GridDemo Project

Launch Xcode and select the option to create a new Multiplatform App project named GridDemo. Once the project has been created, edit the ContentView.swift file to add a custom view to act as grid cell content together with an array of colors to make the grid more visually appealing:

import SwiftUI

 

struct ContentView: View {

         

    private var colors: [Color] = [.blue, .yellow, .green]

.

.

    struct CellContent: View {

        var index: Int

        var color: Color

    

        var body: some View {

            Text("\(index)")

             ...
