Hello @Shahanshah Alam ,
welcome to this moderated Azure community forum.
There is no swift SDK available for the Azure Device Provisioning Service.
All available SDKs are open source and you are welcome to contribute with an SDK specifically for swift.
You can interact with the DPS without an SDK by using the REST API.
As an alternative protocol, you could also use MQTT.
If the response helped, do "Accept Answer". If it doesn't work, please let us know the progress. All community members with similar issues will benefit by doing so. Your contribution is highly appreciated.
