# absoluteURL(withDataRepresentation:relativeTo:)

Initializes and returns a newly created absolute NSURL using the contents of the given data, relative to a base URL.

## Declaration

```swift
class func absoluteURL(withDataRepresentation data: Data, relativeTo baseURL: URL?) -> URL
```

## Discussion

Discussion If the data representation is not a legal URL string as ASCII bytes, the URL object may not behave as expected.
