Set custom selection color in FSCalender for selected dates

Question

Hi I am new to iOS and was working to create a calendar using FSCalendar which is pretty awesome but I am unable to change the selection color of the range of dates in between the first selected date and last selected date. They are all of same colors. I want to display a lighter tone in between the two dates. For Example: Apart from 2nd Dec and 5th Dec in the screenshot screenshot, all the dates should be a different color.

How do I change the color of the dates inside the range excluding the final and initial dates?

By using FSCalendarDelegateAppearance you can control the selection fill color for individual dates.

Step 1. Ensure you have set the delegate:

yourFSCalendarObject.delegate = self

Step 2. Implement available FSCalendarDelegateAppearance delegate methods:

In your case: calendar(_:appearance:fillSelectionColorFor:)

Example:

extension YourClassName: FSCalendarDelegateAppearance {

    func calendar(_ calendar: FSCalendar, appearance: FSCalendarAppearance, fillSelectionColorFor date: Date) -> UIColor? {
        //where startDate and endDate make the range of dates
        if date >= startDate, date <= endDate {
            return .yellow
        } else {
            return nil
        }
    }

}
