I had a similar problem with the Sample code. It builds just fine but when loaded on the iPad to test it fails because the demo did not include the Storyboard files for the Main Window. In Fact, there are no storyboard files included at all in the zip file used for the demo.and this is not the first time this happened with a sample. How are we to execute a demo programme that is lacking major components of its environment? It's not like the demo was put out there yesterday. I am surprised nobody checked their work with the actual distribution copy of the demo sample.
