title: $(ARCHS_STANDARD_32_BIT) vs. armv6, armv7/armv7s vs. i386
body: <p>I have an iPhone App which should run on armv7 as well as armv6. For debugging the App should run in the simulator too.</p>
  
  <p>The Standard in Xcode 4.2 is this:</p>
  
  <p>armv7 (<code>$(ARCHS_STANDARD_32_BIT)</code>)</p>
  
  <p>It is not clear to me what <code>$(ARCHS_STANDARD_32_BIT)</code> stands for and if I should use the two:</p>
  
  <ol>
  <li>$(ARCHS_STANDARD_32_BIT)</li>
  <li>armv6</li>
  </ol>
  
  <p>Or all three like this</p>
  
  <ol>
  <li>armv6</li>
  <li>armv7</li>
  <li>i386</li>
  </ol>
  
  <p>What is the best option for this in my case? And how does <code>Architectures</code> work with <code>Valid Architectures</code></p>
