ios - save a label from Xcode to a user in parse using swift -

-

im trying save label app user class thats created parse when use sign , sign in format. i've tried multiple different ways can't seem find away save data user section. class name user , i'm trying save label column labeled score in user class. code last thing tried do.

@iboutlet weak var label: uilabel!

override func viewdidload() { super.viewdidload() var gamescore = pfobject(classname:"_user")     gamescore["score"] = self.label.text     gamescore.saveinbackgroundwithblock {         (success: bool, error: nserror?) -> void in         if (success) {          } else {          }     }

if me awesome because i'm beyond stumped on this. tried looking on google , youtube , going through parse docs on way but, can't seem figure out.

have checked if object saving?

what saving user class use pfuser.currentuser() obtain user table , save object there. 

let currentuser = pfuser.currentuser(); currentuser.setobject(self.label.text,forkey:"score"); user.saveinbackgroundwithblock{(success,error)-> void in     if(error == nil){         println("success");     }     else{         println("error");     } }
