month-1 does nothing sometimes

[brizzly]

There is an issue when you call previous month method, sometimes it does not go to the desired month-1.

Here is an ugly fix based on previous code..

func setDisplayDate(_ date : Date, animated: Bool) {
	
	if let dispDate = self.displayDate {
		
		// skip is we are trying to set the same date
		if  date.compare(dispDate) == ComparisonResult.orderedSame {
			return
		}
		
		// check if the date is within range
		
		if startDateCache == date {
			return
		}
		if let startDateCache2 = self.calendar.date(byAdding: .month, value: -1, to: startDateCache) {
			if  date.compare(startDateCache2) == ComparisonResult.orderedAscending {
				return
			}
		}
		else
		{
			if  date.compare(startDateCache) == ComparisonResult.orderedAscending {
				return
			}
		}
		
		if  date.compare(endDateCache) == ComparisonResult.orderedDescending   {
			return
		}
		
		
		self.collectionView.setContentOffset(
			self.scrollViewOffset(in: self.collectionView, for: date),
			animated: animated
		)
		
	}
	
}

/*
func setDisplayDate(_ date : Date, animated: Bool) {
	
	// Julien
	if date == startDateCache {
		return
	}
	let newStartDateCache = self.calendar.date(byAdding: .month, value: -1, to: startDateCache)

		
	guard (date > newStartDateCache!) && (date < endDateCache) else { return }
	
	self.collectionView.setContentOffset(
		self.scrollViewOffset(in: self.collectionView, for: date),
		animated: animated
	)
	
	self.displayDateOnHeader(date)
	
}

I checked and I cannot reproduce the problem. Please let me know exactly which dates are you setting in your data source and I will try to replicate it on my side. Remember that the calendar will not scroll past its start and end dates as set by the data source.

Check the latest code as I made some changes, and above all thank you for using my code.

I'm sure there is a bug lol. I have fixed into my code. Swip back is working but not when you call previousMonth method, you stuck 1 month after.

Like I said above, can you let me know exactly which dates are you setting in your data source and I will try to replicate it on my side?

Can you please copy and paste the code from your delegate that returns the start and end?

Can you please zip your project and drop it here so I can have a look?
