# UISplitViewController.Style.unspecified

The split view interface uses the classic split view style.

```
case unspecified
```

## Discussion

A split view controller with this style represents a classic split view controller created using any other approach than [`init(style:)`](/documentation/UIKit/UISplitViewController/init(style:)). You cannot create a split view controller with a style of [`UISplitViewController.Style.unspecified`](/documentation/UIKit/UISplitViewController/Style-swift.enum/unspecified) using this initializer.

Split view controllers with this style don’t support any column-style APIs, such as [`setViewController(_:for:)`](/documentation/UIKit/UISplitViewController/setViewController(_:for:)).
