Getting device twin in Swift Sdk - Azure IoT Hub

Is there a way to get the device twin of a device from Azure IoT-Hub, using Azure SDK for Swift?

As far as I know, I am able to get the device twin using the Azure SDK for NodeJS and also its possible for C and others.

In the documentation it says that the swift sdk is a part of the C sdk. But i didnt know how to get the device twin into swift. I tested with the given code example in the docs but its only how to send messages to the device.

    As per this open issue, as of now, there is no sample available for IoTHubDeviceTwin_GetTwin using Azure SDK for Swift.

    Alternatively, as suggested by Roman, you can get the device twin using REST API.

    GET https://fully-qualified-iothubname.azure-devices.net/twins/{id}?api-version=2020-05-31-preview

    For Swift, you can use AsyncHttpClient 1.6.4, SAS token for authorization header and create it using Device Explorer.
