title: Enum of tuples in Swift
body: <p>Is this possible to create a enum of Tuples in Swift? </p>
  
  <p>I'd like to build something like: </p>
  
  <pre><code>enum ErrorCode: (Int, String) {
      case Generic_Error = (0, "Unknown")
      case DB_Error = (909, "Database")
  }
  </code></pre>
  
  <p>But it doesn't compile... Is there a way to obtain a similar result? </p>
