title: Xcode 5.1: missing required architecture arm64
body: <p>Just upgraded to Xcode 5.1, getting the following error:</p>
  
  <blockquote>
    <p>ignoring file
    ...Dependencies/SalesforceNetworkSDK/libSalesforceNetworkSDK.a,
    missing required architecture arm64 in file
    ...Dependencies/SalesforceNetworkSDK/libSalesforceNetworkSDK.a (3
    slices)</p>
  </blockquote>
  
  <p>If I turn off build active archs only and remove arm64 from valid archs I get:</p>
  
  <blockquote>
    <p>Build/Products/Debug-iphoneos/libPods.a, file was built for archive
    which is not the architecture being linked (armv7)</p>
