Failed to get melted object for frozen object related by key calendar

Question

Hi guys!

I'm implementing a calendar in my app but am having an error I can't seem to figure out.

I fetch all my events with the following code:

class func loadAllEvents(forDate startDate: Date) -> [EKEvent] {

    let calendar = Calendar.current
    let endDate = calendar.date(byAdding: .day, value: 1, to: startDate)

    let eventStore = EKEventStore()
    // Use an event store instance to create and properly configure an NSPredicate
    let eventsPredicate = eventStore.predicateForEvents(withStart: startDate, end: endDate!, calendars: nil)

    // Use the configured NSPredicate to find and return events in the store that match
    let events: [EKEvent] = eventStore.events(matching: eventsPredicate)

    return events
}

then in my tableview I have the following function to load the events in viewdidload:

var dates: [Date] = []
var events: [[EKEvent]] = []

func loadCalendarData() {
    let newDates = Services.returnDatesBetweenInterval(Services.dateFromString("2018-01-22"), Services.dateFromString("2018-02-28"))

    var newEvents: [[EKEvent]] = []
    for date in newDates {
        newEvents.append(Services.loadAllEvents(forDate: date))
    }
    self.dates = newDates
    self.events = newEvents
}

whenever I do a dump(self.events) here, all events have their calendar assigned (event.calendar)

to show them in my tableview's cell I have the following dequeue function:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "calendarEntryCell", for: indexPath) as! CalendarItemTableViewCell

    //check if day has an event, if not display a default label
    if events[indexPath.section].indices.contains(indexPath.row) {
        let event: EKEvent = events[indexPath.section][indexPath.row]
        cell.event = event
        cell.placeHolderCell = false
    } else {
        cell.placeHolderCell = true
    }

    return cell
}

I have the following issue, the first two events have their calendar property set, the rest does not and has a null value!

this is my dumped first event:

- EKEvent <0x1c0117b20>
{
     EKEvent <0x1c0117b20>
{    title =        Grijze container; 
     location =     ; 
     calendar =     EKCalendar <0x1d4c6e380> {title = Prive; type = CalDAV; allowsModify = YES; color = #A32929FF;}; 
     alarms =       (
    "EKAlarm <0x1d02865e0> {triggerInterval = -300.000000}",
    "EKAlarm <0x1d0489600> {triggerInterval = -1800.000000}"
); 
     URL =          (null); 
     lastModified = 2018-01-22 07:27:36 +0000; 
     startTimeZone =    Europe/Amsterdam (CET) offset 3600; 
     startTimeZone =    Europe/Amsterdam (CET) offset 3600 
}; 
     location =     ; 
     structuredLocation =   EKStructuredLocation <0x1d4c68f00> {title = ; address = (null); geo = (null); abID = (null); routing = (null); radius = 0.000000;}; 
     startDate =    2018-01-22 06:30:00 +0000; 
     endDate =      2018-01-22 07:30:00 +0000; 
     allDay =       0; 
     floating =     0; 
     recurrence =   EKRecurrenceRule <0x1d4c68b80> RRULE FREQ=WEEKLY;INTERVAL=2;BYDAY=MO;WKST=SU; 
     attendees =    (
    "EKAttendee <0x1d0c69340> {UUID = 0DAB3E64-1BF6-4BAC-BB39-202996E70588; name = Boris Kamp; email = boriskamp1990@gmail.com; phone = (null); status = 2; role = 1; type = 1}",
    "EKAttendee <0x1d0c69f80> {UUID = 4E734F48-F9F6-4477-BF48-DC5B0FFD4F53; name = (null); email = thari.van.aalst@wereldhave.com; phone = (null); status = 1; role = 1; type = 1}"
); 
     travelTime =   (null); 
     startLocation =    (null);
};

and this is my dumped third event:

EKEvent <0x1c4117c40>
{
     EKEvent <0x1c4117c40>
{    title =        Sportavond; 
     location =     ; 
     calendar =     (null); 
     alarms =       (null); 
     URL =          (null); 
     lastModified = (null); 
     startTimeZone =    Europe/Amsterdam (CET) offset 3600; 
     startTimeZone =    Europe/Amsterdam (CET) offset 3600 
}; 
     location =     ; 
     structuredLocation =   (null); 
     startDate =    2018-01-22 18:30:00 +0000; 
     endDate =      2018-01-22 19:30:00 +0000; 
     allDay =       0; 
     floating =     0; 
     recurrence =   (null); 
     attendees =    (null); 
     travelTime =   (null); 
     startLocation =    (null);
}

aside from the dumped events console prints the following as well:

2018-01-22 13:58:19.769368+0100 DoToo[6285:3411976] [EventKit] Failed to get melted object for frozen object related by key structuredLocationWithoutPrediction. Event store is nil
2018-01-22 13:58:19.769378+0100 DoToo[6285:3411976] [EventKit] Failed to get melted object for frozen object related by key calendar. Event store is nil

How can this happen? I have really no clue and am banging my head on this one for a few hours now.

Thanks in advance!
