iterate through an enum. Not possible but can fake it like this. If you conform to ForwardIndexType you can also use methods like advancedBy and distanceTo

iterate through an enum

enum Number: String, ForwardIndexType {
    case One
    case Two
    case Three
    case Four
    case EndIndex
    
    func successor() -> Number
    {
        switch self {
        case .One:
            return .Two
        case .Two:
            return .Three
        case .Three:
            return .Four
        case .Four:
            return .EndIndex
        case .EndIndex:
            return .EndIndex
        }
    }
}


var number = Number.One
number.advancedBy(2)
number.rawValue

var array: [String] = Array()

while number != Number.EndIndex {
    array.append(number.rawValue)
    number = number.successor()
}

print(array)

for item in array {
    print(item)
}
