Develop a Scrollable Square Grid in Xcode

Using SwiftUI or UIKit, develop a scrollable square grid in Xcode. The interviewer will incrementally increase the requirements: First, develop a scrollable square grid with a fixed number of rows and columns that changes the cell color when a square is clicked. Accept the number of rows and columns externally, and ensure that the color becomes random on each click. Upon clicking, in addition to changing the color, transition to a detail page displaying the new color. Allow color modification on the detail page and return to the previous page. Example Input rows: 3, columns: 3, click sequence: none Output Initial grid with 3x3 squares.
