title: PDFKit class calling deprecated method?
body: <p>I initialized a PDFDocument from a URL, and got the following message:<code>&lt;Error&gt;: CFURLCreateDataAndPropertiesFromResource: failed with error code -15.</code>While I have yet to determine whether or not this "Error code 15" is my bad; I looked up <code>CFURLCreateDataAndPropertiesFromResource</code>, and found it was deprecated in OS X 10.9. I'm a relatively new programmer, so I've steered pretty well clear of deprecated methods. Is it okay to use them? Is there a workaround for this?</p>
