Swift full date with milliseconds

Question

Is any way to print full date with milliseconds?

For example, I'm doing this:

print("\(NSDate())") 

But I'm just get this:

2016-05-09 22:07:19 +0000 

How can I get the milliseconds too in the full date?

Answer 1

Swift 5 to/from Timestamp String Extension

extension String {     static func timestamp() -> String {         let dateFMT = DateFormatter()         dateFMT.locale = Locale(identifier: "en_US_POSIX")         dateFMT.dateFormat = "yyyyMMdd'T'HHmmss.SSSS"         let now = Date()          return String(format: "%@", dateFMT.string(from: now))     }      func tad2Date() -> Date? {         let dateFMT = DateFormatter()         dateFMT.locale = Locale(identifier: "en_US_POSIX")         dateFMT.dateFormat = "yyyyMMdd'T'HHmmss.SSSS"          return dateFMT.date(from: self)     } }

Updated for Swift 3

let d = Date() let df = DateFormatter() df.dateFormat = "y-MM-dd H:mm:ss.SSSS"  df.string(from: d) // -> "2016-11-17 17:51:15.1720" 

When you have a Date d, you can get the formatted string using a NSDateFormatter. You can also use a formatter to turn a string date based on your format into a Date
