# UIDeviceOrientation

Constants that describe the physical orientation of the device.

## Declaration

```swift
enum UIDeviceOrientation
```

## Overview

Overview The orientation property uses these constants to identify the device orientation. These constants identify the physical orientation of the device and aren’t tied to the orientation of your app’s user interface.
