title: Switch universal app to iPhone only app
body: <p>I have Universal app uploaded on app store,</p>
  
  <p>Later based on requirements I have decided to revamp my entire app with iPhone only, so I have created new project in Xcode(with same bundle id) </p>
  
  <p>Now when I try publish my app on the store it shows me this error of <code>Target device family</code> here is the screenshot of error</p>

  <p>I have settled my deployment target to iPhone only in my new project still it shows me error.</p>
  
  <p>Where I am making mistake?</p>
