Convert TimeString yyyy-mm-dd HH:mm:ss to NSDate Time HH:mm AM/PM in swift

Question

I want to convert Time string to NSDate Time into HH:mm: a format. I have a code right now

let defaultStartTime = json!["start_schedule_datetime"] as? String
 let defaultEndTime = json!["end_schedule_datetime"] as? String



                    print(defaultStartTime,defaultEndTime)

                    dispatch_async(dispatch_get_main_queue(), {

                        let dtf = NSDateFormatter()
                        dtf.timeZone = NSTimeZone(name: "UTC")
                        dtf.dateFormat = "HH:mm a"

                        let defaultStartdate : NSDate = dtf.dateFromString(defaultStartTime!)!
                        let defaultEnddate : NSDate = dtf.dateFromString(defaultEndTime!)!

                        print(defaultStartdate,defaultEnddate)

                        self.startTime.date = defaultStartdate
                        self.endTime.date = defaultEnddate
                        self.endTime.reloadInputViews()
                        self.startTime.reloadInputViews()

                        })

Where:-

start_schedule_datetime = 2016-05-27 13:35:00
end_schedule_datetime = 2016-05-27 19:35:00

Here i want time into HH:mm a. But when i am trying to do that i am getting

fatal error: unexpectedly found nil while unwrapping an Optional value

Can any one please help me here. Thank you

You'r date format should be similar to start_schedule_datetime. If you just want to store the date time then store it's converted. Later you can convert it to HH:mm a format for display — Ankita Shah, May 27 '16 at 11:52
@Bhavin Yes i am sure my default defaultStartTime or defaultEndTime is not null — Pushpendra, May 27 '16 at 11:56

Check Below Answer. Both Current date and Date picker date is displaying.

 let dateFormatter = NSDateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd hh:mm a"
    print(dateFormatter.stringFromDate(NSDate())) //if you want current date
    print(dateFormatter.stringFromDate(yourdatepickername.date) //if you want your selective date
