# defaultAppStorage(_:)

The default store used by AppStorage contained within the view.

## Declaration

```swift
nonisolated func defaultAppStorage(_ store: UserDefaults) -> some View

```

## Parameters

- `store`: The user defaults to use as the default store for AppStorage.

## Discussion

Discussion If unspecified, the default store for a view hierarchy is UserDefaults.standard, but can be set a to a custom one. For example, sharing defaults between an app and an extension can override the default store to one created with UserDefaults.init(suiteName:_).
