Make sure you collection class is set to JTAppleCalendarView in Identity Inspector and set the delegate ibCalendarDataSource and ibCalendarDelegate
If your calendar still appears blank make a reload in viewDidLayoutSubviews()
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
calendarView.reloadData()
}
