# sidebarAdaptable

A tab bar style that adapts to each platform.

```
@MainActor @export(implementation) @preconcurrency static var sidebarAdaptable: SidebarAdaptableTabViewStyle { get }
```

## Discussion

Tab views using the sidebar adaptable style have an appearance
that varies depending on the platform:

- iPadOS displays a top tab bar that can adapt into a sidebar.
- iOS displays a bottom tab bar.
- macOS and tvOS always show a sidebar.
- visionOS shows an ornament and also shows a sidebar for secondary tabs within a [`TabSection`](/documentation/SwiftUI/TabSection).

To apply this style to a tab view, or to a view that contains tab views, use
the [`tabViewStyle(_:)`](/documentation/SwiftUI/View/tabViewStyle(_:)) modifier.
