swift – iOS – Add ‘dots’ to UIDatePicker calendar to signify event on date?

I’m using the UIDatePicker calendar in my mobile app. When a user taps on a date (ie. Nov 21), it shows a list of all events happening on that date for the user inside a tableview. Having said that, there doesn’t seem to be any way to add a “dot” on the actual UIDatePicker calendar date to signify that an event exists on it. For example, if I have an array containing a list of dates:

      self.eventDates = @[
        [self dateFromString:@"2023-11-20"],
        [self dateFromString:@"2023-11-25"],
       ];

I’d like a dot to be drawn on the listed UIDatePicker dates.

Has anyone been able to accomplish this? I can’t seem to find examples anywhere. Cheers and thanks!
