How do I format JSON Date String with Swift?

Use the following string format to convert a server string into a Date

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

Nowadays (September 2017) in Swift 4 there are smarter ways to decode ISO8601:

• ISO8601DateFormatter

  let str = "2013-07-21T19:32:00Z"let formatter = ISO8601DateFormatter()let yourDate = formatter.date(from: str)

• JSONDecoder

  struct Place : Decodable {    let name : String    let temperature : Int    let humidity : Int    let reportedAt : Date}let json = """{"name" : "Place1", "temperature" : 79, "humidity" : 68, "reported_at" : "2013-07-21T19:32:00Z"}"""let data = Data(json.utf8)let decoder =  JSONDecoder()decoder.dateDecodingStrategy = .iso8601decoder.keyDecodingStrategy = .convertFromSnakeCaselet place = try! decoder.decode(Place.self, from: data)

If you are using SwiftDate (you probably should!) simply use:

Serialize:

let date:NSDate = ....let dateInRegion = DateInRegion( absoluteTime: date )let serializedString:String = dateInRegin.toString( .ISO8601Format( .Full ))!

Deserialize:

let serializedDate:String = "2016-03-01T22:10:55.200Z"let date:NSDate? = serializedDate.toDateFromISO8601()
