Events don't show on first, main view of calendar

Question

I am using SwiftUI, UIKit and external library CalendarKit in my project. The problem is that events don't load (while initializing ) on first view ( first load ) of calendar ( the current day view ). When I change date in the NavBar, update event or create new event everything works fine. Events are reloading and are showed up on screen.

I have few classes in my projects. First is CalendarScreen which renders the SwiftUI view, ViewModel of CalendarScreen which loads data fetched from API. Service which provides repository and Repository class which runs URLRequest. The UIKit class of DayViewController where everything is going in:

class CalendarViewController: DayViewController {
  convenience init(viewModel: CalendarScreen.ViewModel) {
    self.init()
    self.viewModel = viewModel
  }
  var viewModel = CalendarScreen.ViewModel()
  override func viewDidLoad() {
    super.viewDidLoad()
    reloadData()
  }
  override func reloadData() {
    dayView.timelinePagerView.pagingViewController.children.forEach({ (controller) in
      if let controller = controller as? TimelineContainerController {
        controller.timeline.layoutAttributes = eventsForDate(Date()).map(EventLayoutAttributes.init)
      }
    })
  }
  override func eventsForDate(_ date: Date) -> [EventDescriptor] {
    return viewModel.fetchCalendarEvents { _ in
      var calendarKitEvents = [Event()]
      calendarKitEvents = self.viewModel.calendarEvents.compactMap { item in
        let event = Event()
        event.dateInterval = DateInterval(
          start: self.dateTimeFormat.date(from: item.start) ?? Date(),
          end: self.dateTimeFormat.date(from: item.end) ?? Date())
        event.color = UIColor(InvoiceColor(title: item.title))
        event.isAllDay = false
        event.text = item.title
        return event
      }
      self.eventsOnCeldanr = calendarKitEvents
      return self.eventsOnCeldanr
    }
  }
}

And the classes corresponding to my APICall the main function is func fetchCalendarEvents which return Events to my Controller

class Agent {
  let session = URLSession.shared
  func run<T: Decodable>(_ request: URLRequest) -> AnyPublisher<T, Error> {
    return
      session
      .dataTaskPublisher(for: request)
      .decode(type: T.self, decoder: JSONDecoder())
      .receive(on: DispatchQueue.main)
      .eraseToAnyPublisher()
  }
}

struct CalendarRepository {
  private let agent = Agent()
  func getEvents() -> AnyPublisher<[CalendarEvent], Error> {
    let urlString = "\(calendarurl)"
    let url = URL(string: urlString)!
    var request = URLRequest(url: url)
    request.httpMethod = "GET"
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")
    return agent.run(request)
  }
}

struct CalendarService {
  private var calendarRepository = CalendarRepository()
  func getEvents() -> AnyPublisher<[CalendarEvent], Error> {
    return calendarRepository.getEvents()
  }

  extension CalendarScreen {
    class ViewModel: ObservableObject {
      let calendarService = CalendarService()
      @Published var calendarEvents: [CalendarEvent]
      @Published var events: [Event]
      var cancellable: AnyCancellable?
      init() {
        self.calendarEvents = [CalendarEvent()]
        self.events = []
      }
      func fetchCalendarEvents(_ completion: @escaping ([EventDescriptor]) -> [EventDescriptor])
        -> [EventDescriptor]
      {
        cancellable = calendarService.getEvents()
          .sink(
            receiveCompletion: { _ in },
            receiveValue: {
              calendarEvents in self.calendarEvents = calendarEvents
              NotificationCenter.default.post(name: .onEventLoaded, object: nil)
              self.createEvents()
              completion(self.events)
            })
        return events
      }
      func createEvents() {
        self.events = self.calendarEvents.compactMap({ (item) in
          var event = Event()
          event.dateInterval = DateInterval(
            start: self.dateTimeFormat.date(from: item.start)!,
            end: self.dateTimeFormat.date(from: item.end)!)
          event.color = UIColor(InvoiceColor(title: item.title))
          event.isAllDay = false
          event.text = item.title
          return event
        })
      }
    }
  }
}

So the problem is when I load view for the first time the reloadDate() returning empty [] array.While i try to debug events are in variable calendarKitEvents but without sucessful return t Events don't show up on my calendar.

But when I switch dates lets say for next date and switch back to current day events show up

I am thinking that I don't know how to proper load Events on init view of Calendar. I tried to use reloadData() in every possible moment but without success. Moreover I tried to reloadData() in updateUIViewController. Events show up but it gives me a infinite loop of request to fetch data.
