Remove/change section header background color in SwiftUI List

Question

With a simple List in SwiftUI, how do I change/remove the standard background color for the section header

struct ContentView : View {
    var body: some View {
        List {
            ForEach(0...3) { section in
                Section(header: Text("Section")) {
                    ForEach(0...3) { row in
                        Text("Row")
                    }
                }
            }
        }
    }
}

Answer 1

No need to change appearance of all lists or do anything strange, just:

1. (Optional) Put .listStyle(GroupedListStyle()) on your List if you do not want sticky headers.
2. Set the listRowInsets on the section to 0.
3. Set the Section.backgroundColor to clear to remove the default color, or whatever color you want to color it.

Example:

List {
    Section(header: HStack {
        Text("Header")
            .font(.headline)
            .foregroundColor(.white)
            .padding()

            Spacer()
    }
    .background(Color.blue)
    .listRowInsets(EdgeInsets(
        top: 0,
        leading: 0,
        bottom: 0,
        trailing: 0))
    ) {
        // your list items
    }
}.listStyle(GroupedListStyle()) // Leave off for sticky headers

The suggested solutions works until you decide to clear your List header background color.

Better solutions for List header custom color:

1.This solution effects all of the List sections in your app: (or move it to your AppDelegate class)

struct ContentView: View {

init() {
      UITableViewHeaderFooterView.appearance().tintColor = UIColor.clear
    }

var body: some View {
    List {
        ForEach(0 ..< 3) { section in
            Section(header:
                    Text("Section")
            ) {
                ForEach(0 ..< 3) { row in
                    Text("Row")
                }
            }
        }
     }
  }
}

2.With this solution you can have custom List header background color for each list in your app:

struct ContentView: View {
init() {
    UITableViewHeaderFooterView.appearance().tintColor = UIColor.clear
}

var body: some View {
    List {
        ForEach(0 ..< 3) { section in
            Section(header:
                HStack {
                    Text("Section")
                    Spacer()
                }
                .listRowInsets(EdgeInsets(top: 0, leading: 0, bottom: 0, trailing: 0))
                .background(Color.blue)

            ) {
                ForEach(0 ..< 3) { row in
                    Text("Row")
                }
            }
        }
     }
  }
}
