ios - How to show the current state you are located in when using reverseGeocodeLocation in swift -

i'm testing out reversegeocodelocation app shows closest address. i've gotten work except showing of current state in (il, ny, ext.). how do that? current code:

clgeocoder().reversegeocodelocation(userlocation)     { (placemarks, error) -> void in          if error != nil         {             println(error)         }         else         {             let pm = clplacemark(placemark: placemarks![0] clplacemark)              var subthoroughtare:string = ""             var thoroughfare:string = ""             var sublocality:string = ""             var subadministrativearea:string = ""             var postalcode:string = ""             var country:string = ""              if pm.subthoroughfare != nil {subthoroughtare = pm.subthoroughfare!}             if pm.thoroughfare != nil {thoroughfare = pm.thoroughfare!}             if pm.sublocality != nil {sublocality = pm.sublocality!}             if pm.subadministrativearea != nil {subadministrativearea = pm.subadministrativearea!}             if pm.postalcode != nil {postalcode = pm.postalcode!}             if pm.country != nil {country = pm.country!}             self.addresslabel.text = "\(subthoroughtare) \(thoroughfare) \n \(sublocality) \n \(postalcode) \n \(country)"         }     } 

and output (example location):

 county road 1760    79529   united states 

for state want @ administrativearea

    let state = pm.administrativearea; 

if @ definition clplacemark class shows..

var administrativearea: string! { } // state, eg. ca
