Crash in Day Range Selection horizontal preview

[DavidTomic]

Hi,

Can you fix the crash which happens if you scroll left few months and then very fast scroll right to the first presented month?

The crash happens on this line inside the VisibleItemsDetails struct: return firstLayoutItem.itemType...lastLayoutItem.itemType

with message: Thread 1: Fatal error: Range requires lowerBound <= upperBound

Thank you.
