So Close..

Not sure where I can improve this, it's kind of the most complex version of the combination of code I tried, is it more simpler than this? I tried on Xcode and seems to be working fine on all counts..

enums.swift 
enum Compass: Int {
  case North = 1
  case South = 2
  case East = 3
  case West = 4
}

let direction = Compass.South.rawValue {

if let checkTheCompass = Compass(rawValue: direction) {
print(checkTheCompass)
}

Paul, not quite. You use rawValue a different way, i.e. with Compass' initializer method and the value.:

let direction = Compass(rawValue: 2)

No need for if or print.
