WaterfallGrid don't showing in Navigation View about waterfallgrid

Hi @tuandapen
I've just tried to replicate the issue but I correctly see the grid inside the NavigationView:

struct ContentView: View {
    var body: some View {
        NavigationView {
            WaterfallGrid((0..<10), id: \.self) { index in
                Image(systemName: "photo")
                    .resizable()
                    .aspectRatio(contentMode: .fit)
            }.navigationBarTitle("NavigationView")
        }
    }
}

Xcode: 11.3.1
