# annotation

Custom property list information for the target file.

## Declaration

```swift
var annotation: Any? { get set }
```

## Discussion

Discussion Use this property to pass information about the document type to the app responsible for opening it. Although the type of this object should be one used to contain property list information—namely, NSDictionary, NSArray, NSData, NSString, NSNumber, or NSDate—the root object must be an NSDictionary.
