How to use the document provider extension?

Question

I learned a little more about ios extensions, such as:

• Extension today
• Editing Photos Extension
• Action extension
• Custom Keyboard Extension

In all of them, I had no learning difficulties, but recently I’ve been trying to learn about “expanding the document provider”, and to my surprise, I haven’t found any relevant textbook on the Internet about how to use it (step by step like others).

The only alternative I found is to use the documentation, and I found out that he can access shared documents from other applications, and you can also share your own documents in your application.

The only tutorial I found on the net is the MacStories website, but it uses iCloud, and at this time I don't want to use iCloud, I want the documentation to say:

Allows other applications to access documents managed by your application (without iCloud)

In my case, I already know how the "supplier document extension" works, and so I managed to create a new target type "document provider extension" and only that. Does anyone know how this extension works?

Also one of the best might be ios8 in tutorials on raywanderlich.com, but this one is not free
