title: What should I include in Xcode build settings in "Architectures" section
body: <p>We were supporting iOS 6 &amp; 7 previously for our universal iOS application (which means we support both iPhone and iPad). Now, with the release of iOS 8, we have to support iOS 6, iOS 7 &amp; iOS 8. Also, we have to extend our targeted device list to support iPhone 6 and iPhone 6 Plus. </p>
  
  <p>Also, we are planning to upgrade to Xcode 6 shortly. Because Apple may anytime mandate the use of Xcode 6 to be able to submit apps to app store.  </p>
  
  <p>Keeping all the above points in mind, I am confused what should be my Architecture settings in Xcode build settings. Mainly There are 3 important items under Xcode Architectures settings. Please see the below screenshot. </p>

  <p>I have highlighted the 3 important parameters. I want to know what values I should assign to these parameters in order to support all the above. Any help will be greatly appreciated. I am confused a bit with this. </p>
  
  <p>Also, I would like to know if i need to change anything else in order to migrate to Xcode 6 and iOS 8.</p>
