get user info in facebook sdk 4.x swift

@ibaction func btnfbloginpressed(sender: anyobject) {     var fbloginmanager : fbsdkloginmanager = fbsdkloginmanager()     fbloginmanager .loginwithreadpermissions(["email"], handler: { (result, error) -> void in         if (error == nil){             var fbloginresult : fbsdkloginmanagerloginresult = result             if(fbloginresult.grantedpermissions.containsobject("email"))             {                 self.getfbuserdata()                 fbloginmanager.logout()             }         }     }) }  func getfbuserdata(){     if((fbsdkaccesstoken.currentaccesstoken()) != nil){         fbsdkgraphrequest(graphpath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).startwithcompletionhandler({ (connection, result, error) -> void in             if (error == nil){                 println(result)             }         })     } } 

output :
