I want to convert 2015-08-14T20:02:25-04:00 to 2015-08-14 16:02
I tried below, but it could't execute well(returned nil).

let d = "2015-08-14T20:02:25-04:00"
let formatter = NSDateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss ZZZZ"
let date: NSDate? = formatter.dateFromString(d)

How can I convert this date format?

You need to escape 'T' and use the appropriate timezone symbol. Note that it will depend if your date string represents a UTC (zero seconds from GMT) time timezone with Z "XXXXX" or without it +00:00 "xxxxx":

let dateString = "2015-08-14T20:02:25-04:00"
let formatter = DateFormatter()
formatter.locale = Locale(identifier: "en_US_POSIX")
formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssXXXXX"
if let date = formatter.date(from: dateString) {
    formatter.dateFormat = "yyyy-MM-dd HH:mm"
    let string = formatter.string(from: date)
    print(string)
}

If you need some reference you can use this:
