SwiftUI 透明 TabView（没有背景模糊）？

Question

From what I found on the inte.net, the Tabview in this version of Swift is meant to be transparent.

But in my case it always dispalys a grayish tone with a line on top when there is something underneath it in the view it is displaying. If I scroll down to a space in that view which is empty, the tabview becomes transparent again.

I have been trying to find a solution to this for ages but I'm a absolute noob. Can someone please help me fix this and make it always transparent? Thank you so much!

Use UIBarAppearance.configureWithTransparentBackground() .

struct ContentView: View {
    
    init() {
        let transparentAppearence = UITabBarAppearance()
        transparentAppearence.configureWithTransparentBackground() // 🔑   
        UITabBar.appearance().standardAppearance = transparentAppearence
    }
    
    var body: some View {
        TabView {
            List {
                ForEach(1...40, id: \.self) { eachRowIndex in
                    Text("Row \(eachRowIndex)")
                }
            }
            .listStyle(.plain)
            .tabItem {
                Image(systemName: "house.fill")
                Text("Home")
            }
        }
    }
}
