the pdfkit from the first google result doesn't seem to be related to apple's. what happened here is that "pdfkit" is a very generic name (that will tend to show up because people love writing pdf-related software) that also happens to coincide with apple's convention of naming their frameworks something-kit (uikit, appkit, avkit, ...)
