Unable to add framework using Carthage

[YogendraShelke]

Hi,
I am trying to integrate C3-PRO-iOS-Framework using carthage.
github "C3-PRO/c3-pro-ios-framework.git"
Above line is in Cartfile

On running below command I am getting error which is attached below.
carthage update --platform "iOS"

Carthage may not work since you'll need to add your own public key for the server backend. I'm afraid you'll have to wrestle with git and Xcode a bit to get it going.

The C3PRO framework seems to only be available on carthage in version 1.8.0 not in the current 2.0 version supporting FHIR STU3.
