I would like to create a web application that would have access to the user's Apple Calendar for a personal project. But I really don't want to store the user's password.
With Google it was really easy using OpenAuth.
I know it is definitely possible as SunRise is doing it - http://techcrunch.com/2014/01/31/sunrise-calendar-stops-sending-icloud-credentials-to-their-servers/
I've searched Apple documentation and the closest thing i found was CloudKit. But it looks like it only provides a way to access your App's data across all the places. No mention of iCloud services.
Am i going in the right direction or is there a more direct way of doing this? Or is SunRise bluffing :)
