# WidgetBundle

A container used to expose multiple widgets from a single widget extension.

```
@MainActor @preconcurrency protocol WidgetBundle
```

## Overview

To support multiple types of widgets, add the `@main` attribute to a
structure that conforms to `WidgetBundle`. For example, a game might have
one widget to display summary information about the game and a second
widget to display detailed information about individual characters.

```
@main
struct GameWidgets: WidgetBundle {
   var body: some Widget {
       GameStatusWidget()
       CharacterDetailWidget()
   }
}
```
