Calendar in Swift 3 - ios

Question

enter code hereI'm trying to add a calendar feature to my app, but I'm having 2 errors on two different viewcontrollers, I can't find out what I am missing.
The error says:
Value of type AddEventViewController has no member "Calendar" on the line addEventVC.calendar = calendar
2nd viewcontroller
1st viewcontroller
Code:
import UIKit
import EventKit
class EventsViewController: UIViewController, UITableViewDataSource, EventAddedDelegate {
#IBOutlet weak var tableView: UITableView!
var calendar: EKCalendar!
var events: [EKEvent]?
#IBOutlet weak var eventsTableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
loadEvents()
}
func loadEvents() {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"
let startDate = dateFormatter.date(from: "2016-01-01")
let endDate = dateFormatter.date(from: "2016-12-31")
if let startDate = startDate, let endDate = endDate {
let eventStore = EKEventStore()
let eventsPredicate = eventStore.predicateForEvents(withStart: startDate, end: endDate, calendars: [calendar])
self.events = eventStore.events(matching: eventsPredicate).sorted {
(e1: EKEvent, e2: EKEvent) in
return e1.startDate.compare(e2.startDate) == ComparisonResult.orderedAscending
}
}
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if let events = events {
return events.count
}
return 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "basicCell")!
cell.textLabel?.text = events?[(indexPath as NSIndexPath).row].title
cell.detailTextLabel?.text = formatDate(events?[(indexPath as NSIndexPath).row].startDate)
return cell
}
func formatDate(_ date: Date?) -> String {
if let date = date {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM/dd/yyyy"
return dateFormatter.string(from: date)
}
return ""
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let destinationVC = segue.destination as! UINavigationController
let addEventVC = destinationVC.childViewControllers[0] as! AddEventViewController
addEventVC.calendar = calendar
addEventVC.delegate = self
}
// MARK: Event Added Delegate
func eventDidAdd() {
self.loadEvents()
self.eventsTableView.reloadData()
}
}
AddEventViewController :
class AddEventViewController: UIViewController {
#IBOutlet weak var eventNameTextField: UITextField!
#IBOutlet weak var eventStartDatePicker: UIDatePicker!
#IBOutlet weak var eventEndDatePicker: UIDatePicker!

// Do any additional setup after loading the view, typically from a nib.
self.eventStartDatePicker.setDate(initialDatePickerValue(), animated: false)
self.eventEndDatePicker.setDate(initialDatePickerValue(), animated: false)
}
func initialDatePickerValue() -> Date {
let calendarUnitFlags: NSCalendar.Unit = [.year, .month, .day, .hour, .minute, .second]
var dateComponents = (Calendar.current as NSCalendar).components(calendarUnitFlags, from: Date())
dateComponents.hour = 0
dateComponents.minute = 0
dateComponents.second = 0
return Calendar.current.date(from: dateComponents)!
}

You are calling addEventVC.calendar = calendar but your AddEventViewController doesn't have a variable called calendar which is why you get the error AddEventViewController has no member "Calendar".
