The project generated using Cocos2D already contains some code that we can see in action, so let's make sure that Xcode is targeting the simulator and run the project, before making any changes. To do this, perform the following steps:
Switch to Xcode and take a look at the top-left corner of the Xcode window, as shown in the following screenshot:
Click on the iPhone label marked with the black square as shown in the previous screenshot. It will open a drop-down list similar to what is shown in the following screenshot:
Here, we can see the different simulators we can run our project on. Let's select iOS 7.1 by navigating to iPhone Retina (4-inch) | iOS 7.1 and click on the Run button (command + R).
