struct Booking{

  let bookingNumber:String
  let bookingCompleted:Bool
  let cancelledBy:[String:AnyObject]?

       init(bookingNumber:String,
          bookingCompleted:String){
         self.bookingNumber = bookingNumber
         self.bookingCompleted = bookingCompleted
        }

      init(cancelledBy:[String:AnyObject]){
           self.cancelledBy = cancelledBy
        }
}

class DisbursePayment {

   override func viewDidLoad() {
    super.viewDidLoad()
   //how to handle if cancelledBy is nil? It will throw error :  unexpectedly 
   //found nil while unwrapping an Optional value
   //How should I structure my data in `struct Booking`?
   let item = Booking(cancelledBy: valueCouldBeNil)  
  }
}
