How to Update Date In FsCaldener in Swift Ios?

Question

How to update date in fscalender initially while launching an app. i am updating the date while scrolling fscalender but my doubt initially loading app how to send date to Post service Call?

This is my api for getting dates from server.

let now2 = NSDate() 
let dateFormatter2 = DateFormatter() 
dateFormatter2.dateFormat = "yyyy" 
let nameOfyear = dateFormatter2.string(from: now2 as Date)
print("nameOfyear",nameOfyear)
let urlString = Fetch_Parent_Dashboard_Calendar_URL+"&year="+nameOfyear+"&mo‌​nth="+nameOfMonth+"&‌​branch_id=" + Userbranchid!

i am taking date value from user defaults sending to server when user scrolling fscalender.Following is the code for sending date to server when scrolling fscalender.

func calendar(_ calendar: FSCalendar, didSelect date: Date, at monthPosition: FSCalendarMonthPosition) 
{
   let dateFormatter2 = DateFormatter() 
   dateFormatter2.dateFormat = "dd/MM/yyyy" 
   let nameOfDate = dateFormatter2.string(from: date as Date)
   print("nameOfDate",nameOfDate) 
   UserDefaults.standard.set(nameOfDate, forKey: "nameOfDate")
}

My doubt is initially loading the app i have to send current date and scrolling time have to send that user defaults time how to handle date at this case

If i understood correctly you have to do like this.

Make generic function to call web service with the given date

func callWebServiceWithDate(date:Date)
{
  let dateFormatter = DateFormatter() 
  dateFormatter.dateFormat = "yyyy" 
  let nameOfyear = dateFormatter.string(from: date)
  dateFormatter.dateFormat = "MM"
  let nameOfMonth = dateFormatter.string(from: date)
  let urlString = Fetch_Parent_Dashboard_Calendar_URL+"&year="+nameOfyear+"&mo‌​nth="+nameOfMonth+"&‌​branch_id=" + Userbranchid!
}

Now call this method from viewDidLoad or viewWillAppear method with Date() as input parameter for initial call.

override func viewDidLoad()
{
   super.viewDidLoad()
   self.callWebServiceWithDate(date: Date())
}

And call the same method from FSCalendars delegate method

func calendar(_ calendar: FSCalendar, didSelect date: Date, at monthPosition: FSCalendarMonthPosition) 
{
   self.callWebServiceWithDate(date: date)
}
