# appearance

The appearance of the receiver, in an `NSAppearance` object.

```
var appearance: NSAppearance? { get set }
```

## Discussion

The default value for this property is `nil`, which means that the receiver uses the appearance it inherits from the nearest ancestor that has set an appearance. When you set `appearance` to a non-`nil` value, the receiver and the views it contains use the specified appearance.
