Enumerate enums - Getting all values in an enum

It sounded strange to me, but there is no way to enumerate all the cases of an enum automatically baked in the language. As an example I had this enum for three different strings that corresponded to 3 Identifiers of NSToolbarItems:

 enum Identifier: String {
  case General = "General"
  case Network = "Network"
  case Advanced = "Advanced"
  }

And I need to enumerate them so I can tell the toolbar which items are selectable and which aren’t. By the way, I have no idea which this method returns an array of AnyObject instead of an array of String, as it should do — but I’m digressing.

So I added a new property in the enum called allValues ¹

:

  func toolbarSelectableItemIdentifiers(toolbar: NSToolbar) -> [AnyObject] {
    return //?
  }

So I changed the enum to include a property that contains all of them — not the most beautiful thing to see, but it gets it done.

  enum Identifier: String {
  case General = "General"
  case Network = "Network"
  case Advanced = "Advanced"
    
    static let allValues = [General, Network, Advanced]
  }

So now we can do:

 func toolbarSelectableItemIdentifiers(toolbar: NSToolbar) -> [AnyObject] {
 return Identifier.allValues
 }
