I'm trying to use a closed range for a computed property in an enum but it's not working. Like this ...
enum example {
case a, b, c
var index : 1...3
switch self {
case .a : return 1
case .b : return 2
case .c : return 3
}
}


but this doesn't compile. What am I doing wrong ? I'm trying to use a closed range as a type to help enforce strong typing and reduce potential for bugs. Thank you.
