Getting the wrong date in Formatted array

Hi,

I use xCode 8 and swift 3 and therefore I need to make a couple of changes to det the code to compile correctly.

struct Formatter {
    static let formatter = DateFormatter()

    static func dateFromString(dateString: String) -> NSDate? {
        formatter.dateFormat = "d MMM yyyy"
        return formatter.date(from: dateString) as NSDate?
    }
}

let dateStrings = ["10 Oct 1988", "11 Jan 1947", "28 Mar 2002"]

let dates = dateStrings.map { Formatter.dateFromString(dateString: $0) }

I think this is correct? The problem I get is that the array of NSDate? Types is wrong I always get a day short

[Optional(1988-10-09 23:00:00 +0000), Optional(1947-01-10 23:00:00 +0000), Optional(2002-03-27 23:00:00 +0000)]

I am in Sweden so my local settings is a little different than the one in the video. But as you can se I get 9-okt-1988 instead of 10-okt-1988, and it’s the same error on the other dates as well
