[iCloud] Calendars without supported-calendar-component-set restriction don't accept events and tasks

  • developer

    For reference and transparency: We have created this report on Apple Bug Reporter on 23 Feb 2016 here: https://bugreport.apple.com/web/?problemID=24791955

    When creating a calendar by MKCALENDAR without supported-calendar-component-set, iCloud doesn’t set without supported-calendar-component-set by itself.

    So the without supported-calendar-component-set property stays undefined, which means (RFC 4791):

    “In the absence of this property, the server MUST accept all component types, and the client can assume that all component types are accepted.”

    Steps to Reproduce:

    1. Create CalDAV collection with MKCALENDAR. Don’t specify supported-calendar-component-set.
    2. Use PROPFIND to verify that supported-calendar-component-set is not set.

    Expected Results:
    iCloud doesn’t show this collection as “Calendars” and “Reminders”, but only as one of them.

    Actual Results:
    CalDAV calendars without supported-calendar-component-set should show up as both “calendars” and “reminders”.

    direct CalDAV requests (curl/command line)


    This issue behaves as intended based on the following:

    The first VOBJECT - VEVENT or TODO will decide the type of this container.

    Please update your bug report to let us know if this is still an issue for you.

    Our response:

    I understand this, but I think it’s against the CalDAV specification and just wanted to report it.
