String enumerations in swift 2.1

Question

I am reading swift 2.1 iBook about enumeration

The example :

enum CompassPoint: String {
  case North, South, East, West
}

gives me

<stdin>:3:8: error: enum cases require explicit raw values when the raw type is not integer literal convertible
case North, South, East, West

demo

I am not sure if documentation is outdated or some issue with compiler

Answer 1

The error comes from the online compiler you're using because it's in Swift 1.2 by default and you're using Swift 2 code.

There's a "Swift 1.2" button in the lower right corner of the site page, change it to "Swift 2 (beta)" and the error will disappear.
