Implement an iOS scrollable grid with navigation

You are building a small iOS prototype in Xcode (Swift). You may use SwiftUI or UIKit.

Implement a scrollable square grid of cells.

Incrementally add the following requirements:

1. Fixed grid
   • Render a grid with a fixed number of rows/columns.
   • Each cell is a square.
   • Tapping a cell changes that cell’s color.
2. Configurable dimensions + random color
   • The number of rows/columns is provided externally (e.g., initializer parameters).
   • Each tap changes the tapped cell to a random color .
3. Navigate to a detail screen
   • After tapping a cell, also navigate to a detail screen that displays the new color.
4. Edit in detail and propagate back
   • On the detail screen, allow changing the color.
   • When navigating back, the updated color must be reflected in the grid.

Discuss:

• Data model/state management
• How you would structure navigation
• How you would ensure cells remain square while scrolling
