swift - Get [String] from NSUserDefaults.standardUserDefaults().dictionaryRepresentation().keys -

-

nsuserdefaults.standarduserdefaults().dictionaryrepresentation().keys returns [nsobject] need (and expect) [string]. coffee i'm missing?

that returns lazybidirectionalcollection<mapcollectionview<dictionary<key, value>, key>>. can add .array array instance back, use map cast values string:

let keys = nsuserdefaults.standarduserdefaults().dictionaryrepresentation().keys.array.map { $0 string } println(keys) // [nslanguages, nsinterfacestyle, applelanguages]
