Returning nil when converting string to date in swift

Question

My date format in string is "2019-03-28".

My date formatter is like "yyyy-MM-dd"

let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd"
dateFormatter.timeZone = TimeZone(abbreviation: "GMT+0:00")
let assignDate = dateFormatter.date(from: deliveryDate)

What am I doing wrong here

let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd"
dateFormatter.timeZone = TimeZone(abbreviation: "GMT+0:00")
let assignDate = dateFormatter.date(from: "2019-03-28")
print("assignDate \(assignDate)")

All works fine for me here!

assignDate Optional(2019-03-28 00:00:00 +0000)

Its returning nil for me. – Vishnu Prasannan Aug 25 '20 at 03:51
can you please put the date in code without variable and test it. (I think that in your deliveryDate isn't a format that you wait) – Alexander Nikolaychuk Aug 25 '20 at 03:53
I have looked upon my data its coming as 2019-03-28. When I do this without a variable it is getting the date. Why is that happening? – Vishnu Prasannan Aug 25 '20 at 04:08
try to print a deliveryDate before putting it to formatter. I think it is just deliveryDate is a empty String – Alexander Nikolaychuk Aug 25 '20 at 04:09
so assignDate is a nil? – Alexander Nikolaychuk Aug 25 '20 at 04:15
But let me clarify. It is OK if you will put hardcoded string instead of deliveredDate? – Alexander Nikolaychuk Aug 25 '20 at 04:18
try printing assignDate and check its count. – Leo Dabus Aug 25 '20 at 04:24
I know that you provide the image, but can you please add a print with the delivered date? If it is working with hardcoded string but not working now - there is only one variable - delivered data. (Maybe it has some spaces or etc). Please print it before putting in formatter – Alexander Nikolaychuk Aug 25 '20 at 04:24
Where you get this deliveredDate? can you provide peace of JSON (or whatever) when you get this? (I think is a has some strange signs) – Alexander Nikolaychuk Aug 25 '20 at 04:29
@VishnuPrasannan check the string data `Data(assignDate.utf8)` – Leo Dabus Aug 25 '20 at 04:33
Guys it worked. I dont know what happened I just restart Xcode and now its running fine. Tons of thanks to both @AlexanderNikolaychuk – Vishnu Prasannan Aug 25 '20 at 04:56

let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd"
dateFormatter.timeZone = TimeZone(abbreviation: "GMT+0:00")
let assignDate = dateFormatter.date(from: deliveryDate)

This is working fine
