# write(_:)

Writes the serialized contents of the specified file wrapper to the pasteboard.

## Declaration

```swift
func write(_ wrapper: FileWrapper) -> Bool
```

## Parameters

- `wrapper`: The file wrapper to write to the pasteboard.

## Return Value

Return Value true if the data was successfully written, otherwise false.

## Discussion

Discussion Writes the serialized contents of the file wrapper wrapper to the receiver and declares the data to be of type NSFileContentsPboardType and also of a type appropriate for the file’s extension (as returned by the NSCreateFileContentsPboardType function when passed the files extension), if it has one. If wrapper does not have a preferred filename, this method raises an exception.
