# accessibilityValue(_:isEnabled:)

Adds a textual description of the value that the tab contains.

```
@export(implementation) nonisolated func accessibilityValue(_ valueResource: LocalizedStringResource, isEnabled: Bool = true) -> some TabContent<Self.TabValue>
```

## Parameters

`valueResource`

The accessibility value to apply.

`isEnabled`

If true the accessibility value is applied; otherwise
the accessibility value is unchanged.

## Discussion

Use this method to describe the value represented by a tab, but only
if that’s different than the tab’s label such as when an icon represent
information about a tab.

```
var body: some View {
    TabView {
        Tab {
            MessagesView()
        } label: {
            Text("Messages")
        }
        .badge(30)
        .accessibilityValue("30 Unread")
    }
}
```
