First of all playground example that demonstrates the problem:

import UIKit
import SwiftUI
import PlaygroundSupport

struct MyList: View {
    
    var body: some View {
        content
    }
    
    private var content: some View {
        List {
            Section {
                Text("hello")
            }
            .background(Color.red) // This only changes small area around text. Looking for Workaround 2
        }
        .background(Color.blue) // This doesn't work (Workaround 1)
        .foregroundColor(Color.yellow)
    }
    
    init() {
        
        // Workaround 1 - works
        UITableView.appearance().backgroundColor = .blue
        
        // Workaround 2 - nothing below helps
        UITableView.appearance().sectionIndexTrackingBackgroundColor = .green
        UITableView.appearance().sectionIndexBackgroundColor = .green
        UITableViewCell.appearance().backgroundColor = .green
        UITableViewCell.appearance().backgroundView = nil
        UITableViewCell.appearance().backgroundConfiguration = .clear()
    }
}

let viewController = UIHostingController(rootView: MyList())

// Present the view controller in the Live View window
PlaygroundPage.current.liveView = viewController

Explanation:

• View has a List, which I need to change background for. There's a well-known workaround to change it via UITableView.appearance().backgroundColor, which is what I do. So far so good.
• I also need to change the background of the section. In the image below I want the entire section to be red, not white. White should not exist at all:

But I can't find the way to achieve this. If I add .background(Color.red) to the Section, it only changes the small area around the text. OK, but if the white area is not part of List, and not Section then what is the rest of the white area?

I tried various workarounds found in SO, as listed under // Workaround 2 - nothing below helps. None of them help.

So my question is, simply put, how do I get rid of white area in this layout.

Note:

• I would prefer to not switch away from List, unless it's the only option.
• Answers involving introspect are fine too.

Change:

.background(Color.red) // This only changes small area around text. Looking for Workaround 2

To:

.listRowBackground(Color.red)
