SOLVED: Background Color of a list, make it clear color.

This used to work, but as of iOS14 beta 5, there is a white space behind the "cells". Any idea how to get rid of the white space?

struct ContentView: View {
    var body: some View {

        let items = ["Donald", "Daffy", "Mickey", "Minnie", "Goofy"]

        UITableView.appearance().backgroundColor = .clear
        UITableViewCell.appearance().backgroundColor = .clear

        return NavigationView {
            ZStack {
                Color.red
                    .edgesIgnoringSafeArea(.all)
                List {
                    ForEach(items, id: \.self) { item in
                        NavigationLink(destination: DetailView(item: item)) {
                                ItemCell(item: item)
                                .frame(height: 50)
                            }

                    }
                }
            }
        }
    }
}

struct DetailView: View {
    var item: String

    var body: some View {
        Text(item)
    }
}

struct ItemCell: View {

    var item: String
    var body: some View {

        ZStack {

            RoundedRectangle(cornerRadius: 10)
                .fill(LinearGradient(gradient: Gradient(colors: [Color.green, Color.blue]), startPoint: .topLeading, endPoint: .bottomTrailing))
                .clipShape(RoundedRectangle(cornerRadius: 10))
                .padding(.horizontal, 4)
                .shadow(color: Color.black, radius: 3, x: 3, y: 3)

            HStack(alignment: .center) {
                Text(item)
            }.font(.body)
        }
    }
}

Interesting. If you change "List" to "Scrollview", it looks like it should (and you can get rid of the UITableView items. But is that the best way to do it?

ForEach(items, id: \.self) { item in
                        NavigationLink(destination: DetailView(item: item)) {
                                ItemCell(item: item)
                                .frame(height: 50)
                            }
                    }.listRowBackground(Color.red)

	@ShadowDES Aug '20 Thanks DimNovo And no, I would never use that color scheme in a public project. 3
	@DimNovo Aug '20 No problem ShadowDES If you expect to get changes in some object's properties - you have to call this property... I don't quite understand - about 'that color scheme'? `Color.clear` it's OK too in this case. 3
	@cliff-in-auld-reekie Oct '20 `I've been wrestling with this and have a static list working nicely:` `struct ClearCell: ViewModifier { func body(content: Content) -> some View { content .offset(x: -20) .padding(.horizontal) .font(.system(size: 18, weight: .bold, design: .rounded)) .foregroundColor(.black) .listRowBackground(Color.clear) } }` Then in my View body I have this inside a ZStack (for a background image) inside GeometryReader and it works. List { Text("Thing") .frame(width: geo.size.width, alignment: .leading) .modifier(ClearCell()) Text("Another Thing") .frame(width: geo.size.width, alignment: .leading) .modifier(ClearCell()) Text("And Another Thing") .frame(width: geo.size.width, alignment: .leading) .modifier(ClearCell()) Text("Yet Another Thing") .frame(width: geo.size.width, alignment: .leading) .modifier(ClearCell()) } .frame(width: geo.size.width, height: geo.size.height) .offset(x: -50.0,y: -50.0) .onAppear() { UITableView.appearance().backgroundColor = UIColor.clear UITableViewCell.appearance().backgroundColor = UIColor.clear } I do seem to need to interfere with both TV and TVCell appearances for success. However, change the list to dynamic from an array - .... struct AnItem with id: UUID and descr: String and it all goes white again. :-( `List(items, id: \.id ) { item in Text(item.descr) .frame(width: geo.size.width, alignment: .leading) .modifier(ClearCell()) } .frame(width: geo.size.width, height: geo.size.height) .offset(x: -50.0,y: -50.0) .onAppear() { UITableView.appearance().backgroundColor = UIColor.clear UITableViewCell.appearance().backgroundColor = UIColor.clear }` I hope it helps. I'm still digging but it does feel like List is a tad iffy, in this respect, in XCode 12.0.1 and iOS 14.0.1 3
	@DavidGagne Oct '20 FWIW: I'm working on converting my UIKit app to SwiftUI and have been banging my head against this problem for days. The `body` of my `ContentView` is a `NavigationView`, which wraps a `FilteredView` (see Dynamically filtering @FetchRequest with SwiftUI). The `body` of my `FilteredView` wraps a `List` which wraps a `ZStack` which wraps my detail view stacked on a `NavigationLink` (to avoid displaying the default `List` disclosure indicator). Regardless of what combinations of different solutions I attempt, it seems like there's no way to make the `List` transparent and / or to (consistently) apply a background color to it. 3
	@DavidGagne Oct '20 I've gotten this to work (for now). I'll update as I make progress on my `List` and change it from a simple one to one using more complex views in case it stops working. `init() { UITableView.appearance().separatorStyle = .none UITableViewCell.appearance().backgroundColor = UIColor(Color.red) UITableView.appearance().backgroundColor = UIColor(Color.red) }` (And, no, my app isn't really using a red background!) 3
	@piotrros Oct '20 How to do in SwiftUI 2.0?: `let withIndex = entries.enumerated().map { $0 } List(withIndex, id: \.element.id) { index, entry in Button(action: { //do something }) { Text(entry.first) }.listRowBackground(Color.clear) }` Background is still white. 3
	@piotrros Oct '20 Got it working, even though people say in iOS 14 List doesn't use UITableView this was the missing piece: `UITableView.appearance().backgroundColor = .clear UITableViewCell.appearance().backgroundColor = .clear` Anyone knows how to hide or make separator full width (now it appears with left padding)? 3
	@JeneaVranceanu Sep '21 Looks like the problem of a `List` view is that it only takes into consideration the `ColorScheme`. Changing the `ColorScheme` from light to dark changes the background color from white to black. `List { ... }.colorScheme(.dark) // Or List { ... }.colorScheme(.light)` And there is no way to not use the color scheme or provide a custom implementation. Correct me about the last statement if I'm wrong. 3
