CVCalendarView disappears

[ghost]

Xcode 7.2, Swift 2.0. I added two UIViews (with custom classes CVCalendarView and CVCalendarMenuView) as well as required delegates to UIViewController in Storyboard. Here is my code inside the VC:

import UIKit
import CVCalendar

class ViewController: UIViewController, CVCalendarMenuViewDelegate, CVCalendarViewDelegate {

    @IBOutlet weak var menuView: CVCalendarMenuView!
    @IBOutlet weak var calendarView: CVCalendarView!


    override func viewDidLoad() {
        super.viewDidLoad()

    }

    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()

        calendarView.commitCalendarViewUpdate()
        menuView.commitMenuViewUpdate() 
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func presentationMode() -> CalendarMode {
        return CalendarMode.MonthView
    }

    func firstWeekday() -> Weekday {
        return Weekday.Monday
    }
}

Problem is that Calendar View disappears. I don't see the view anymore when I run the project. Menu View works fine. It doesn't look like it is an Auto Layout problem. What can cause the issue?

Found the reason. The following condition in CVCalendarView.commitCalendarViewUpdate() is evaluated to false:

let allowed = selfSize.width <= screenSize.width && selfSize.height <= screenSize.height

when the constraints for CVCalendarView from left/right are less than zero:

I fixed the constrains and the calendar appears now.
