In the chapter entitled [[Creating a Simple iPhone iOS 6 App]] we were able to run an application in the iOS Simulator environment bundled with the iOS 6 SDK. Whilst this is fine for most cases, in practice there are a number of areas that cannot be comprehensively tested in the simulator. For example, no matter how hard you shake your computer (not something we actually recommend) or where in the world you move it to, neither the accelerometer nor GPS features will provide real world results within the simulator (though the simulator does have the option to perform a basic virtual shake gesture and to simulate location data). If we really want to test an iOS application thoroughly in the real world, therefore, we need to install the app onto a physical iPhone device.
