title: SwiftUI 2 clear background for list section header
body: <p>SwiftUI 2 broke a part of my app that relied on a clear background for a List section header. Previously I relied on this line to make the list sections clear. Does anyone know how to accomplish this in SwiftUI 2?</p>
  <pre><code>UITableViewHeaderFooterView.appearance().tintColor = .clear
  </code></pre>
  <p>Here is a sample that would work in SwiftUI 1:</p>
  <pre><code>struct ContentView: View {
  
      var body: some View {
          List {
              Section(header:
                  Text(&quot;List Header&quot;)
              ) {
                  Text(&quot;Hi&quot;)
              }
              .listRowBackground(Color.clear)
          }
          .onAppear {
              UITableViewCell.appearance().backgroundColor = UIColor.clear
              UITableViewHeaderFooterView.appearance().tintColor = .clear
          }
      }
  }
  </code></pre>
  <p>Desired: <code>List Header</code> should be transparent and not grey.</p>
