# isAvailable

Indicates when the tab sidebar is available to be displayed in the current context. When available, the sidebar is either visible, or
can become visible depending on `isHidden`. Use this property to gate behaviors or UI that is dependent on the availability of
the sidebar (like child tabs, or landing pages for groups).

```
var isAvailable: Bool { get }
```

## Discussion

Implement the delegate method `tabBarController:sidebarAvailabilityDidChange:` to be notified when the value of this property changes.
