I've made my first application which ran fine on my iPod touch and on my iPad. Now I'm in the process of making my second app, but Xcode won't let me run the app on my device. When I plug in the device, it just does't pop up in the device menu (where you choose the simulator etc.), but it still works fine on my first app. Is there any additional configuration I have to do?
Yes, you have to be sure that you have installed a provisioning profile that match your application's identifier.
