Swift enum both a string and an int
With Swift 4.2 this can be done using CaseIterable. One, relatively concise way is to do the following
enum Directions: String, CaseIterable {
case north, south, east, west
static var asArray: [Directions] {return self.allCases}
func asInt() -> Int {
return Directions.asArray.firstIndex(of: self)!
}
}
print(Directions.asArray[2])
// prints "east\n"
print(Directions.east.asInt())
// prints "2\n"
print(Directions.east.rawValue)
// prints "east\n"
I think this will do it for me. Thank you self.. :)
