# UITabBarController.Sidebar.Layout.overlap

When the sidebar is displayed, it will overlap the selected view controller, allowing the selected view controller to render underneath the sidebar. Anchor the view’s content to the layoutMarginsGuide or safeAreaLayoutGuide to avoid being occluded by the sidebar.

## Declaration

```swift
case overlap
```
