问题
I have always run with the assumption that Google delegates can be viewed by iCal and the calendar.app, but are not visible to us developers through the calendar framework, or EventKit.
Has this changed?

Apparently its a problem on google's side. They claim to be "working on it" Check discussion
I found the google thread on another apple forum page devoted to the same problem:Here
