# EmptyModifier

An empty, or identity, modifier, used during development to switch modifiers at compile time.

## Declaration

```swift
@frozen nonisolated struct EmptyModifier
```

## Overview

Overview 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     } }
