滚动时不透明的背景工具栏

Question

I have opaque the background of the TabBar but not the ToolBar when I expected both...

.onAppear{
    let tabBarAppearance = UITabBarAppearance()
    tabBarAppearance.configureWithOpaqueBackground()
    UITabBar.appearance().standardAppearance = tabBarAppearance
    let toolBarApperance = UIToolbarAppearance()
    toolBarApperance.configureWithOpaqueBackground()
    UIToolbar.appearance().standardAppearance = toolBarApperance
    UIToolbar.appearance().scrollEdgeAppearance = toolBarApperance
  } 

Some hint plis;)

toolbarBackground(_:for:) solves the problem but only in iOS 16

if #available(iOS 16.0, *) {
  ...
  .toolbarBackground(Color.black, for: .automatic)
}
