Choose the Use Storyboard option in the New Project setting dialog (Figure 4-1) and make your app a universal app.
If you want to create a project that uses storyboards, simply follow these steps:
In Xcode, select the File menu and then New→New Project...
In the New Project dialog, make sure the iOS main category is selected and select the Application subcategory under iOS. Once that is done, on the right side, select Single View Application and press Next, as shown in Figure 4-2.
Now select a product name and make sure your app is a Universal app. Apple wants developers to start writing universal apps whenever they can, in order for iPad users to also enjoy the same apps that iPhone and iPod touch users have access to. In this dialog, make sure you have checked the User Storyboards checkbox, as shown in Figure 4-3. After you are done, press Next.
You will now be asked to save your project in a folder. Once you are done, press the Create button (see Figure 4-4) and now you have a project that uses storyboards.
Now if you have a look at the files that Xcode has created for you (see Figure 4-5), you’ll notice two files whose names end with .storyboard. Xcode, because this is a universal app, created a storyboard for iPhone and another storyboard for iPad, so you can dictate how you want your app to look on each device family.
