# writableContentTypes

The content types this document can save or export to.

```
static var writableContentTypes: [UTType] { get }
```

## Discussion

a document also conforms to [`ReadableDocument`](/documentation/SwiftUI/ReadableDocument), the
default implementation returns [`readableContentTypes`](/documentation/SwiftUI/ReadableDocument/readableContentTypes).
