# WidgetBundleBuilder

A custom attribute that constructs a widget bundle’s body.

## Declaration

```swift
@resultBuilder struct WidgetBundleBuilder
```

## Overview

Overview Use the @WidgetBundleBuilder attribute to group multiple widgets listed in the body property of a widget bundle. For example, the following code defines a widget bundle that consists of two widgets. @main struct GameWidgets: WidgetBundle {    @WidgetBundleBuilder    var body: some Widget {        GameStatusWidget()        CharacterDetailWidget()    } }
