To authenticate the Proto iOS SDK, complete the following steps:

  1. Authenticate the user to get the access token in order to use other mobile APIs:

        print("False with code: \(String(describing: err?.mErrorCode)) and message: \(err?.mErrorMessage)")
    print("accessToken: " + (authResponse?.accessToken)! + " userId " + (authResponse?.userId)!)
  1. Get the User ID:
let userId = PTUserService.getInstance().getUserId()
  1. Get the access token:
let accessToken = PTUserService.getInstance().getAccessToken()
  1. Get the gateway ID:
let gatewayId = Proto.getInstance().getGatewayId()
  1. Get the Firebase device token:
