If I am not wrong, FSCalendar is developed in Objective-C and can be used in Swift application using bridging headers. So to use it, efficiently in Swift based iOS application, I recommend creating a manager class .h and .m file and then using the manager class in Swift application. This will help you keep all your delegates of FSCalendar including its properties in the manager class itself.

Implement the below delegate method to change the color of the particular date:

-(UIColor *)calendar:(FSCalendar *)calendar appearance:(FSCalendarAppearance *)appearance titleDefaultColorForDate:(NSDate *)date
{
    NSInteger day = [[[NSCalendar currentCalendar] components: NSCalendarUnitWeekday fromDate: curDate] weekday];
    if(day == 1) //Sunday
    {
        return [UIColor redColor];
    }

    return [UIColor blackColor]; //Considering default date color is black
 }

For disabling selection, please use below delegate method

-(BOOL)calendar:(FSCalendar *)calendar shouldSelectDate:(nonnull NSDate *)date atMonthPosition:(FSCalendarMonthPosition)monthPosition
{
    NSInteger day = [[[NSCalendar currentCalendar] components: NSCalendarUnitWeekday fromDate: curDate] weekday];
    if(day == 1) //Sunday
    {
        return NO;
    }

    return YES;
}

This is very basic code to give you idea and direction in which you may want to move forward to achieve the customization you want.
