@frozen nonisolated struct EmptyModifier

An empty, or identity, modifier, used during development to switch modifiers at compile time. Use the empty modifier to switch modifiers at compile time during development. In the example below, in a debug build the ``Text`` view inside `ContentView` has a yellow background and a red border. A non-debug build reflects the default system, or container supplied appearance. struct EmphasizedLayout: ViewModifier { func body(content: Content) -> some View { content .background(Color.yellow) .border(Color.red) } } struct ContentView: View { var body: some View { Text("Hello, World!") .modifier(modifier) } var modifier: some ViewModifier { #if DEBUG return EmphasizedLayout() #else return EmptyModifier() #endif } }
