I have an iPad-only app (targeted device family is iPad, architecture is armv7), but Xcode offers both iPhone & iPad simulators to deploy to in the scheme/device dropdown. If I create a new iPad-only project from scratch, only iPad Simulator is available as a deployment target.
Why does my iPad-only project show iPhone Simulator as a device option?
In case you have a tests target too, make sure in its build settings that the Targeted Device Family is set to iPad as in your app's target. This might sound silly, but I have seen it before.
Then, as stated in the other answers, check the same option for any sub-project's target you may have included in your app's project.
Do a quick search of your target's build settings for "Universal" and change this to iPad if necessary. That's the ONLY reason why this would be happening. The only other thing I can suggest is restarting your computer. Sometimes Xcode has even given me Mac build options for iOS apps! If none of that works, well, if it ain't broke don't fix it, as in if you can build and test it in the iPad Simulator, what's the problem??
This might be occurring if you have initially started a universal app, and changed it at a later time without readjusting the settings. Just change the settings (click on the main project folder and update the settings) and there should be no problem. You can also simply create a new iPad app and copy all your files there. You can select the iPad device family to deploy your app on, and it should remember that setting every time you run it, so don't bother changing it or figuring out why it allows you to deploy on both devices; as long as it's working, keep on programming and testing.
