I am trying to convert a NSDate to a String and then Change Format. But when I pass NSDate to String it is producing whitespace.

 let formatter = DateFormatter()
 let myString = (String(describing: date))
 formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
 let yourDate: Date? = formatter.date(from: myString)
 formatter.dateFormat = "dd-MMM-yyyy"
 print(yourDate)

let formatter = DateFormatter()
// initially set the format based on your datepicker date / server String
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"

let myString = formatter.string(from: Date()) // string purpose I add here 
// convert your string to date
let yourDate = formatter.date(from: myString)
//then again set the date format whhich type of output you need
formatter.dateFormat = "dd-MMM-yyyy"
// again convert your date to string
let myStringafd = formatter.string(from: yourDate!)

print(myStringafd)

you get the output as
