# hasAppearanceStream

Returns a Boolean value that indicates whether the annotation has an appearance stream associated with it.

```
var hasAppearanceStream: Bool { get }
```

## Return Value

<doc://com.apple.documentation/documentation/Swift/true> if the annotation has an appearance stream; otherwise <doc://com.apple.documentation/documentation/Swift/false>.

## Discussion

An appearance stream is a sequence of draw instructions used to render a PDF item. If an appearance stream exists, PDF Kit draws the annotation using the stream, which may override existing set parameters (such as the stroke color set with `setColor`).
