I am using Event Kit to read and create events. I want to be able to add attendees to such events. But as described in documentation we cannod do that with Event Kit framework:
Event Kit provides limited access to a user’s Calendar database; it does not include everything that would be desired for implementing a full-featured calendar or reminder app, such as adding attendees or accounts (Link to the source)
I see that some apps, like Google Calendar, can do that. I think that they are using CalDAV protocol, but I could not find anything about that (documentation, tutorials, other helpfull resources) and I don't know where to start.
Any help would be welcome. Thanks

Anyway, I will try to post here my research updates.
