Sms Verification with Sinch swift 3

Question

Hi Im using Sinch sms verification to sign up users in my app but after updating my code to swift 3 (and sinch sdk currently 2.0.3), Im getting the following error

Cannot convert value of type '(Bool, NSError?) -> Void' to expected argument type '(Bool, Error?) -> Void'

I know that if I change NSError to Error , this error disappear

Sinch Verification Swift 3

but I need to get the error code from the NSError to alert my user on what happened depend on this error

   if (result.success){
          //login user
         } else {
            if error!.code == 6 {
                   let msg = NSLocalizedString("This Phone Number is invalid",
                         comment: "This Phone Number is invalid pop up alert")
                   print(msg)
            }
   } 

From Sinch Docs , Im suppose to use this NSError:

https://www.sinch.com/docs/verification/ios/#swiftsdk

 let verification = SMSVerification(applicationKey:"<APP KEY>", phoneNumber: phoneNumberInE164)
    verification.initiate { (result: InitiationResult, error: NSError?) -> Void in
        // handle outcome
    }

Is there a way to get the error.code from error:Error? Thanks for your help
