Most of ios apps are written in objective-c. I am surprised to see there is no objective-c for v2. I don't know what is in their head when they made such decision.
Thank you for your feedback, Abi. We're currently tracking this as a feature request, though we have nothing to announce at the moment.
The official Objective-C SDK for API v2 has been released here:
