Convert Optional string to date

Question

I have this Optional(2015-07-27 19:29:50 +0000) as a string? and I want to convert it to a date (NSDate) but I can't figure it out I've been searching a lot for solutions but I am pretty new to coding so if anyone could help I would appreciate it.

This is what I am using to convert the string to a date currently.

note: dateString is Optional(2015-07-27 19:29:50 +0000)

dateFormatter = NSDateFormatter()
println(dateFormatter)
dateFormatter.dateFormat = "yyyy-MM-dd"
let s = dateFormatter.dateFromString(dateString)

I always get a nil value

The question should be more generic, like "Convert string to data", you also do not need to add tags in your question, as they are displayed further down. Finally you should also so in what context and what you've tried so far. — Emz, Jul 27 '15 at 19:19

If you are getting nil from NSDateFormatter, you likely specified incorrect date format. Try this:

let strTime = "2015-07-27 19:29:50 +0000"
let formatter = NSDateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss Z"
formatter.dateFromString(strTime) // Returns "Jul 27, 2015, 12:29 PM" PST

Might mention if it's for the Swift class `Date` to use `DateFormatter` instead. – Dean Kelly Jan 13 '17 at 23:10

You will want to use a NSDateFormatter and call dateFromString: on it to get the date from the string. See Apple's NSDateFormatter documentation for a great explanation of doing what you want.

In swift 3.0:

let strTime = "2015-07-27 19:29:50 +0000"
let formatter = NSDateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss Z"
formatter.date(from: strTime)

dateString is already date and need to convert to string. Below code is working fine

dateFormatter = NSDateFormatter() println(dateFormatter) dateFormatter.dateFormat = "yyyy-MM-dd" let s = dateFormatter.string(from: dateString)
