# fileWrapper

The text attachment’s file wrapper.

## Declaration

```swift
var fileWrapper: FileWrapper? { get set }
```

## Discussion

Discussion The file wrapper holds the contents of the attached file. In iOS, modifying this property has a side effect of invalidating the image, contents, and fileType properties.
