Use NSSerialization.datawithJSON in Swift 2

Question

Been trying to get this to work in Swift 2.0, the error says:

Type NSJSONWritingOptions cannot conform to protocol NilLiteralConvertible

Answer 1

let options = prettyPrinted ? 
         NSJSONWritingOptions.PrettyPrinted : NSJSONWritingOptions(rawValue: 0)

is the right syntax for swift 2.0
