How to convert date which is having String type to NSDate?

Question

I am developing an iOS app using Swift. I am accessing data from server and it is returning data in JSON format. In that I am having a field 'ExpiryDate' which is getting from that JSON and converted to string as follows:

var validityDate = offerElements[indexPath.row]["endDate"].stringValue

It is returning date of following format:

2015-08-24T00:00:00.000Z

I wanna convert it to MM/DD/YYYY, how can I do it ?

Your suggestions are most welcome. Thank you in advance.

I have tried to use this : var validityDate = offerElements[indexPath.row]["endDate"].stringValue var currentDate = NSDate(validityDate) var dateString = dateFormatter.stringFromDate(validityDate) @Dipen, But it is throwing error : Cannot find an initializer for type 'NSDate' that accepts an argument list of type '(String)' — Chetan Purohit, Sep 30 '15 at 05:44
@ChetanPurohit of course it will, you can't directly type cast string to date. first convert your string to date using `NSDateFormatter` then again convert that date to your desired format. i hope its clear to you. — Dipen Panchasara, Sep 30 '15 at 05:46
@ChetanPurohit To me, it gave this result on top: http://stackoverflow.com/questions/24777496/how-can-i-convert-string-date-to-nsdate (Existing Stack Overflow question, 35 up votes as of now.). Google _**is**_ your friend. — Nicolas Miari, Sep 30 '15 at 05:53

This should work with minimal or no changes

    func dateFromString(dateString: String) -> NSDate {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"

        return dateFormatter.dateFromString(dateString)!
    }

check once your dateformat is wrong , check the milli seconds on questioner output , please update – Anbu.Karthik Sep 30 '15 at 05:51
Can you explain what's wrong in that? I – Sahil Kapoor Sep 30 '15 at 05:53
check the updated comment, but i am not give the downvote , – Anbu.Karthik Sep 30 '15 at 05:53
That is zone (time zone), not milliseconds. Z at the ends signifies that. – Sahil Kapoor Sep 30 '15 at 05:54
the date format comes --yyyy-MM-dd'T'HH:mm:ss.SSSZ – Anbu.Karthik Sep 30 '15 at 05:58
Z worked for me, but thanks, updated the answer. – Sahil Kapoor Sep 30 '15 at 06:07
Don't put the `Z` in quotes in the format string. Doing so will cause the date to be parsed in local time instead of UTC time. – rmaddy Sep 30 '15 at 06:07
Thank you Anbu.Karthik and Sahil.. :-) – Chetan Purohit Sep 30 '15 at 06:08

And the hour needs to be `HH`, not `hh`. – rmaddy Sep 30 '15 at 06:08
@ChetanPurohit Don't use this answer in its current form. It's still incorrect. – rmaddy Sep 30 '15 at 06:09
I wrote it should work with minimal changes, HH is for 24 hours format, and hh for 12 hours. But I totally agree, HH should be used. Thanks. – Sahil Kapoor Sep 30 '15 at 06:11
But you are still incorrectly quoting the `Z` in the format. That's bad. Don't quote it. It's the timezone specifier and must not be quoted. – rmaddy Sep 30 '15 at 06:12
Hey guys, I have done changes as per my requirement and it is working fine for me.. – Chetan Purohit Sep 30 '15 at 06:13
You should NOT escape the Z. Doing this the date will be interpreted as local time when it is actually UTC time. You should use X instead of Z. "yyyy-MM-dd'T'HH:mm:ss.SSSX" – Leo Dabus Sep 30 '15 at 06:18
