# init(contentsOf:)

Provides data-backed content from an existing file.

```
convenience init?(contentsOf fileURL: URL!)
```

## Parameters

`fileURL`

The URL of the file to use for the item provider’s data. The item provider uses the filename extension to determine the universal type identifier for the associated data.

## Return Value

An item provider for the specified file, or `nil` if an error occurs.

## Discussion

The system uses the URL’s filename extension to select an appropriate universal type identifier. If the system can’t determine a specific universal type identifier based on the filename extension, it assigns the `public.data` universal type identifier for the file.
