Unable to perform functions from Particle iOS Cloud SDK after downloading Xcode 8 / Swift 3.0 -

prior downloading xcode 8 able perform functions particle ios cloud sdk (spark sdk) without problem. now, being given multiple errors similar ones below.

sparkcloud.sharedinstance().loginwithuser(username!, password: password!) { (error:nserror?) -> void in              // deactivates activity indicator.             activityindicator.stopanimating()              // reallows interaction events.             uiapplication.sharedapplication().endignoringinteractionevents()              if error != nil {                  utils.showalertonvc(self, title: "invalid parameters.", message: "please try again.")                 self.cleartext()              } else {                  self.performseguewithidentifier("loginuser", sender: self)              }          } 

error: cannot convert value of type '(nserror?) -> void' expected argument type 'sparkcompletionblock?'

sparkcloud.sharedinstance().getdevices { (sparkdevices: [anyobject]?, error: nserror?) -> void in          if let sparkdevices = sparkdevices as? [sparkdevice] {              device in sparkdevices {                  self.myphotons.append(device)                 self.tableview.reloaddata()              }          }      } 

error: cannot convert value of type '([anyobject]?, nserror?) -> void' expected argument type '(([any]?, error?) -> void)?'

i've tried updating podfile , toying function calls nothing seems work. i'm wondering if has updates in swift 3.0 can't find indicate so. issue appreciated.

instead of nserror, use error:

sparkcloud.sharedinstance().getdevices { (sparkdevices: [anyobject]?, error: error?) 

this did trick me.
