error : cannot subscript value of type [clplacemark] index type int

import uikit import corelocation  class viewcontroller: uiviewcontroller, cllocationmanagerdelegate {      let locationmanager = cllocationmanager()  override func viewdidload() {     super.viewdidload()     // additional setup after loading view, typically nib.      self.locationmanager.delegate = self     self.locationmanager.desiredaccuracy = kcllocationaccuracybest     self.locationmanager.requestwheninuseauthorization()     self.locationmanager.startupdatinglocation()  }  override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }    func locationmanager(manager: cllocationmanager, didupdatelocations locations: [anyobject]) {     clgeocoder().reversegeocodelocation(manager.location!, completionhandler: { (placemarks, error) -> void in          if (error != nil) {             print("error")             return         }          if placemarks!.count > 0 {             let pm = placemarks[0] clplacemark             self.displaylocationinfo(pm)         }         else {             print("errordata")         }      }) }  func displaylocationinfo(placemark: clplacemark){     self.locationmanager.stopupdatinglocation()      print(placemark.locality)     print(placemark.postalcode)     print(placemark.administrativearea)     print(placemark.country) }  func locationmanager(manager: cllocationmanager, didfailwitherror error: nserror) {     print("error:" + error.localizeddescription)      } }

no, in xcode 7 error is:

error: cannot subscript value of type '[clplacemark]?' index of type 'int'

note of ?. have unwrap optional. can replace:

if placemarks!.count > 0 {     let placemark = placemarks[0] clplacemark     self.displaylocationinfo(placemark) }

with:

if let placemark = placemarks?.first {     self.displaylocationinfo(placemark) }
