How to change Event Dot Color in FSCalender - swift3

Question

Here is my code. I am trying to change the dot color but I did not find any solution. Thanks
func calendar(_ calendar: FSCalendar, numberOfEventsFor date: Date) -> Int {
return 1;
}
func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, eventColorFor date: Date) -> UIColor? {
return UIColor.red
}
Here is an example image of these event-dots:

This example is taken from here. Basically you just use the given method, check for event-type or something like that and return a color of your favour.
//Used by one of the example methods
var datesWithEvent = ["2015-10-03", "2015-10-06", "2015-10-12", "2015-10-25"]
var datesWithMultipleEvents = ["2015-10-08", "2015-10-16", "2015-10-20", "2015-10-28"]
//Used in one of the example methods
fileprivate lazy var dateFormatter2: DateFormatter = {
let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd"
return formatter
}()
The complete example is to long for embedding, so i only took 2 example methods. I added the fields from the example, to have an "complete" example of how such a method could look like.
func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, eventColorFor date: Date) -> UIColor? {
//Do some checks and return whatever color you want to.
return UIColor.purple
}
func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, eventDefaultColorsFor date: Date) -> [UIColor]? {
let key = self.dateFormatter2.string(from: date)
if self.datesWithMultipleEvents.contains(key) {
return [UIColor.magenta, appearance.eventDefaultColor, UIColor.black]
}
return nil
}
For better understanding have a look at linked example class in Github. That example is pretty self explanatory.
