DateFormatter returns nil

Question

Why does DateFormatter return nil? I think the string format matches?

let dateString = ("01/05/2017")!
let dateFormatter = DateFormatter()
dateFormatter.timeZone = TimeZone.current
dateFormatter.dateFormat = "dd/MMM/yyyy"
let dateObj = dateFormatter.date(from: dateString)

After executing the code above, the dateObj is nil.

That simply means that the string does not match the date format. – Apple provides a [Data Formatting Guide](https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/DataFormatting/Articles/dfDateFormatting10_4.html#//apple_ref/doc/uid/TP40002369-SW1) which links to the [Date Format Patterns](http://www.unicode.org/reports/tr35/tr35-31/tr35-dates.html#Date_Format_Patterns) documentation. — Martin R, Jun 02 '17 at 12:15
`let dateString = ("01/05/2017")!` looks so ugly. What are you trying to unwrap there? There is no optional value in a regular string. — Leo Dabus, Jun 02 '17 at 12:17
change your String from `let dateString = ("01/05/2017")!` to let dateString = "01/05/2017" — Anbu.Karthik, Jun 02 '17 at 12:18
Well, this is embarassing. I just had a typo in my code. Thanks for all the help :) — Teun Vos, Jun 02 '17 at 15:27

For month you need to use MM because MMM is used when you having month in the format like Jan,Feb,Mar and so on. So your dateFormat should be dd/MM/yyyy.

let dateString = "01/05/2017"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateObj = dateFormatter.date(from: dateString)

Note: No need to set timeZone to TimeZone.current

Replace with your dateFormat:

dateFormatter.dateFormat = "dd/MM/yyyy"
