使用Sinch swift进行短信验证3

Question

您好我使用Sinch短信验证在我的应用程序中注册用户但在将我的代码更新为swift 3（和sinch sdk目前2.0.3）后，我收到以下错误

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

我知道如果我将NSError更改为Error，则此错误消失

Sinch Verification Swift 3

但我需要从NSError获取错误代码，以提醒我的用户发生了什么事情取决于此错误

   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)
            }
   } 

来自Sinch Docs，我想要使用这个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
    }

有没有办法从错误中获取error.code：错误？ 谢谢你的帮助

let verification = SMSVerification(applicationKey:"<APP KEY>", phoneNumber: phoneNumberInE164)
    verification.initiate { (result: InitiationResult, error: Error?) -> Void in
        // handle outcome
        if (result.success){
          //login user
         } else if let error = error as? NSError, error.code == 6 {
            let msg = NSLocalizedString("This Phone Number is invalid",
                         comment: "This Phone Number is invalid pop up alert")
            print(msg)
         }
    }
