fixed data, so why list all cases

Since there are only 7 values, why do you have to list all the cases? Why not just sat, sun = weekend, and some key word like "else" or "otherwise"-- weekday.

You can do that. See the following example:

func weekdayOrWeekend(day: Day) -> String {
    switch day {
    case .Saturday, .Sunday: return "Weekend"
    default: return "Weekday"
    }
}

and call it like this:

weekdayOrWeekend(.Monday) // Returns Weekday
weekdayOrWeekend(.Saturday) // Returns Weekend

In the code above, only Saturday and Sunday would return Weekend, and all other Day values passed in would return Weekday. Hope that helps illustrate the point! Let me know if you have another other questions.

You can, but they probably are showing you the different cases so you can see how it works with more cases. Once you understand the concept, you can always simplify.
