Getting error Expected ':' after 'case'. Any ideas? 

enum Day{
    case Monday
    case Tuesday
    case Wednesday
    case Thursday
    case Friday
    case Saturday
    case Sunday
}

func weekdayOrWeekend(dayOfWeek: Day) -> String{
    switch dayOfWeek {
        case Day.Monday, Day.Tuesday, Day.Wednesday, Day.Thursday, Day.Friday
            return "It's a weekday"
        case Day.Saturday, Day.Sunday
            return "It's a weekend!"
        default:
            return "Not a valid day"
    }
}

I am using swift 2.0. Is there a new syntax for cases in 2.0? If I add the ':' I just get new errors

Hi Morgan,

The colon goes after the case statement not the keyword:

func weekdayOrWeekend(dayOfWeek: Day) -> String{
    switch dayOfWeek {
        case Day.Monday, Day.Tuesday, Day.Wednesday, Day.Thursday, Day.Friday: //<- here
            return "It's a weekday"
        case Day.Saturday, Day.Sunday: // <- and here
            return "It's a weekend!"
        default:
            return "Not a valid day"
    }
}

That works for me.

Steve.
