What makes PDF so successful is that it is a proven technology, the specification is public and platform-independent, and PDF files can be both compact and secure. In short, PDF has become a de facto standard in the world because it makes it easy for users to create, distribute, and view documents. This article provides an overview of developing with PDF Kit and the benefits it provides, and helps you get started as quickly as possible.”
It’s certainly very handy from the user perspective having PDF built into the OS.
Kinda like translators for common file formats.
I don’t develop for any Microsoft operating systems so I don’t know if they put out quality developer articles like this, but I know that I love these articles from Apple. The quality of these articles are amazing and they really are a great jumping off point for using the various “kits”, i.e. libraries and frameworks, that Apple lets developer use (for free!).
