Facing an error of Swift.String : Swift.Error in heresdk

I have Project where I have already integrated heresdk since 2 years back and it is working fine but when I update to latest heresdk then it gives an following error

protocol conformance descriptor for Swift.String : Swift.Error in heresdk

I have tried everything possible since last 2 months but not able to fix this error. IT will be a great support if someone could help me.

Thanks.
