inaccessible due to 'internal' protection level swift 3 - ios

Question

I am getting this error "'removeCircleLabel' is inaccessible due to 'internal' protection level" on this line of code. I was adding CVCalendar Library to my project.I added the pod but i when i am adding the view controller code in my project that time its giving me this error.
#IBOutlet weak var calendarView: CVCalendarView!
#IBAction func removeCircleAndDot(sender: AnyObject) {
if let dayView = selectedDay {
calendarView.contentController.removeCircleLabel(dayView)// **error on this line**
if dayView.date.day < randomNumberOfDotMarkersForDay.count {
randomNumberOfDotMarkersForDay[dayView.date.day] = 0
}
calendarView.contentController.refreshPresentedMonth()
}
}
public typealias ContentViewController = CVCalendarContentViewController
public final class CVCalendarView: UIView {
// MARK: - Public properties

}
// MARK: Delete circle views (in effect refreshing the dayView circle)
extension CVCalendarContentViewController {
func removeCircleLabel(_ dayView: CVCalendarDayView) {
for each in dayView.subviews {
if each is UILabel {
continue
} else if each is CVAuxiliaryView {
continue
} else {
each.removeFromSuperview()
}
}

Answer 1

By default all the methods, variable, constants, etc are internal. With internal protection level those methods, variable, constants, etc are not accessible outside a module.
removeCircleLabel(:_) is an internal method of the calendar module, you need make it public to access it.
Also do read: What is the 'open' keyword in Swift?
This explains when you should use public and open.

Answer 2

In my quick search i found the function removeCircleLabel in CVCalendarContentViewController on GitHub.
// MARK: Delete circle views (in effect refreshing the dayView circle)
extension CVCalendarContentViewController {
func removeCircleLabel(_ dayView: CVCalendarDayView) {
for each in dayView.subviews {
if each is UILabel {
continue
} else if each is CVAuxiliaryView {
continue
} else {
each.removeFromSuperview()
}
}
}
}
it clearly you can access this method from your controller. There is no protection.Please check your calendarView source with latest one.
