Cannot Signin to QuickBlox iOS 13

I am trying to Signin using QuickBlox SDK 2.17.1 with iOS 13 using below code

    let login = "saifan"
    let password = "quickblox"
    QBRequest.logIn(withUserLogin: login,
                    password: password,
                    successBlock: { [weak self] response, user in
                        guard let self = self else {
                            return
                        }

                        Print("Success")

        }, errorBlock: { [weak self] response in
           Print("Error")  
    })

this is working fine in iOS 12 but getting following error only in iOS 13

Please update your Quickblox sdk to the latest version (QuickBlox 2.17.4) if you are using Xcode 11. I was also facing the same issue. After the update the issue got fixed.
