# init(contentsOf:fileTypeHint:)

Creates a player to play audio from a file of a particular type.

## Declaration

```swift
init(contentsOf url: URL, fileTypeHint utiString: String?) throws
```

## Parameters

- `url`: A URL that identifies the local audio file to play.
- `utiString`: The uniform type identifier (UTI) string of the file format.

## Return Value

Return Value A new audio player instance, or nil if there is an error.

## Discussion

Discussion The audio data must be in a format that Core Audio supports. Passing a file type hint helps the system parse the data if it can’t determine the file type or if the data is corrupt. See AVFileType for supported values.
