Crash when loading insane amount of events on one day.

[ph1lb4]

When showing a great amount of events (screenshot attached), the CalendarView crashes. The last line of the code below crashes with EXC_BAD_INSTRUCTION:

open func getCurrentEvent(with indexPath: IndexPath) -> JZBaseEvent? {
    let date = flowLayout.dateForColumnHeader(at: indexPath)
    return isAllDaySupported ? notAllDayEventsBySection[date]?[indexPath.row] : allEventsBySection[date]?[indexPath.row]
}

I don't believe it is a good idea to show that many events, therefore a good fix may be to allow a "more events" cell that shows when 3 or 4 events are at the same time. Another approach may be the solution by Apple, where they overlay certain items, but it also gets very confusing with many events.

I haven't encountered this situation, could you send me your event data?

Sure, so these are the events (the use case is actually a list of all the events for SXSW this year, we show them in a different view as well thought). Let me know if you need anything else 👍 Here is a Json parsable output:

Hi, I'm also facing this crash, can you help me on how to avoid this case, I'm not even using much data.

[zjfjack]

@yashlangaliya I am currently fixing this issue, could you send me your data to test?
