let tableView = UITableView(frame: .zero, style: .insetGrouped)
The code above would result in a table view with rounded corners and are inset from the edges of the parent view.
SwiftUI has a List view to represent rows or data, just like UITableView. Too bad it doesn't have inset grouped style. You has only two styles (for iOS)

You can make your grouped lists style present as an inset grouped style by overriding your list view with regular horizontal size class (
Apple choose not to introduce a new style like
InsetGroupedListStyle, but adapt

In iOS 14, we finally have dedicated style for inset group,
