What should be the format of a string to convert into NSDate?

I'm getting following two types of strings from server:

  1. 2016-07-28T12:25:31.922247
  2. 2016-07-28T13:39:13

I want to convert them into NSDate. I'm using following snippet to convert but it's failing:

let dateFormatter = NSDateFormatter()
dateFormatter.timeZone = NSTimeZone(name: "UTC")
dateFormatter.dateFormat = "yyyy-MM-ddTHH:mm:ss"

I'm not getting the desired output.

If you doesn't care the fraction of second then you can remove it like this.

var strDate = "2016-07-28T12:25:31.922247"
if strDate.rangeOfString(".") != nil{
     let arr = strDate.characters.split{$0 == " "}.map(String.init)
     strDate = arr[0]
}
//Now you can convert this string to date using same date format
let formatter= NSDateFormatter()
formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
let date = formatter.dateFromString(strDate)

Your date format works in 2016-07-28T13:39:13 but add 'T'

Example: yyyy-MM-dd'T'HH:mm:ss.

But for the 2016-07-28T12:25:31.922247 you need clarifies that this means 922247

the truth had never seen anything like it, but I would try with yyyy-MM-ddTHH:mm:ssZ

You need to quote the "T" (or any alpha characters that should be present in literal form), try:

let dateFormatter = NSDateFormatter()
dateFormatter.timeZone = NSTimeZone(name: "UTC")
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"

Note that this will only parse your second string. To parse your first string you'll need to use:

dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.S"

if you care about the fractional seconds. Since NSDateFormatter is a literal parser it doesn't allow you to easily parse either format, if you have to parse both you'll just need to pass it to one, if that fails pass to the other.

You can get the exact format from this Link

For the second string use this 

yyyy-MM-dd'T'HH:mm:ss
