swift - Access String value in enum without using rawValue -

i replace global string constants nested enum keys i'm using access columns in database.

the structure follows:

enum databasekeys {      enum user: string {         case table = "user"         case username = "username"         ...     }      ...  } 

each table in database inner enum, name of table being enum's title. first case in each enum name of table, , following cases columns in table.

to use this, it's pretty simple:

myuser[databasekeys.user.username.rawvalue] = "johnny" 

but using these enums a lot. having append .rawvalue every instance pain, , it's not readable i'd be. how can access string value without having use rawvalue? it'd great if can this:

myuser[databasekeys.user.username] = "johnny" 

note i'm using swift 2. if there's better way accomplish i'd love hear it!

while didn't find way using desired syntax enums, possible using structs.

struct databasekeys {      struct user {         static let identifier = "user"         static let username = "username"     }  } 

to use:

myuser[databasekeys.user.username] = "johnny" 

apple uses structs storyboard , row type identifiers in watchkit templates.
