The final step is to build and run the application. In order to fully test the pinching and rotation recognition it will be necessary to run the application on a physical device (since it is not possible to emulate two simultaneous touches within the iOS Simulator environment). Assuming a provisioned device is attached (see [[Testing iOS 6 Apps on the iPad – Developer Certificates and Provisioning Profiles]] for more details) simply click on the Xcode Run button. Once the application loads on the device, perform the appropriate gestures on the display and watch the status label update accordingly.
