I'm just getting started with Objective C and RestKit.

I created an application and added the RestKit project. I use RestKit to load en map JSON data from my webserver.

The application runs fine in the simulator and on my iPhone device. Now I want to create a TestFlight beta. I have setup a distribution certificate and added it to my phone and Code Signing settings.

Now I want to generate the IPA. I use the Archive option under the Project menu item. When I click's this button occurs the following error:
