The method dateFromString returns an optional. If the conversion fails, it returns a nil. You are getting a nil, so there must be something wrong with your format string.

I don't use date format strings often enough to have them memorized, so I'd have to go read the specs. I suggest you do that.

The date format in the question matches the date string. – rmaddy Apr 30 '16 at 01:38
This would have been better suited as a comment. – rmickeyd Apr 30 '16 at 01:40
@zetanova How was it incorrect? `dd-MM-yyyy` matches a string like `02-05-2016`. – rmaddy Apr 30 '16 at 02:02
