I am trying to retrieve emails from participants in a calendar event. The documentation (https://developer.apple.com/documentation/eventkit/ekcalendaritem/1507140-attendees) states that this information is provided as as an array of EKParticipant objects. But, in reality, I get an array of EKAttendee objet. This object is not documented. It contains the information I'm looking for (email) but I can't find any way to retrieve it. Have you ever faced this problem? How to retrieve the email of the participants?
