You create a Table of Contents (AKA Outlines, Bookmarks) using PDFKit's PDFOutline object. You can also read existing Outlines within a PDF.

In the absence of existing Outlines, I'm not sure there's a way to get meaningful data from the PDF stream itself, e.g. trying to grok Chapter headings just from the PDF data.
