swift - Change background color of TextEditor in SwiftUI

Question

TextEditor seems to have a default white background. So the following is not working and it displayed as white instead of defined red:

var body: some View {
    TextEditor(text: .constant("Placeholder"))
        .background(Color.red)
}

Is it possible to change the color to a custom one?

TextEditor is backed by UITextView. So you need to get rid of the UITextView's backgroundColor first and then you can set any View to the background.

struct ContentView: View {
    init() {
        UITextView.appearance().backgroundColor = .clear
    }

    var body: some View {
        List {
            TextEditor(text: .constant("Placeholder"))
                .background(Color.red)
        }
    }
}
