After Xcode finishes building your project, Simulator should start automatically (you might have to wait a few seconds for Simulator to appear on top of the workspace window). Because you specified an iPhone product (rather than an iPad product), Simulator displays a window that looks like an iPhone. On the simulated iPhone screen, Simulator opens your app, which should look like this:
../Art/first_run.jpg
Right now, your app is not very interesting: it simply displays a blank white screen. To understand where the white screen comes from, you need to learn about the objects in your code and how they work together to start the app. For now, quit Simulator (choose iOS Simulator > Quit iOS Simulator; make sure that you don’t quit Xcode).
When you run your app, Xcode might open the Debug area at the bottom of the workspace window. You won’t use this pane in this tutorial, so you can close it to make more room in your window.
