Error about return enum.case.rawValue

In the beginning of the video Mr. Amit's code has no error in the function daysTillWeekend. In my code it says "Day does not have a member named 'rawValue'. Will someone help me?

Hi arnavthecoder,

In order for an enum to register the property rawValue you need to assign an explicit type to it which matches the initial case value, for example.

enum Days: Int {
    case Monday = 1, Tuesday, Wednesday, Thursday, Friday,
        Saturday, Sunday
}

println(Days.Monday.rawValue)

In the above example I've assigned the type Int which initialises the rawValue property and sets a requirement that the first case statement must have a value, because I've used an Int type all I need to do is set the first case statement to 1 and Swift will do the rest, for strings we need to define each value.

Hope that helps.

I had the same problem, looks like .rawValue has been changed to .toRaw() by Swift
