title: How Single App Binary Supports 64-bit and 32-bit Apps
body: <p>We can see apple announcement <a href="https://developer.apple.com/news/" rel="nofollow noreferrer">here.</a>. According to this doc, we can submit same binary with supporting 32-bit and also 64-bit. I found one stack overflow answer <a href="https://stackoverflow.com/questions/18913906/xcode-5-and-ios-7-architecture-and-valid-architectures">here</a>. But According to this answer, we <code>should</code> set <code>deployment target as IO7+</code>. But apple doc said, you can submit this with IOS 7 and IOS 6 support? My question is, <strong>How can we generate binary with supporting 32-bit and 64-bit by deployment target IOS6+?</strong></p>
  
  <p><strong>Note:</strong> I'm using <code>xcode 5.0</code></p>
  
  <p><strong>Update:</strong> <code>Question above is fixed by using xcode 5.0.2</code>. But I get confused how can I make code for 32-bit as well 64-bit. I know one thing, we must do code for two separately in some times. But <code>How can I do?</code>. for example, if one method in deprecated in ios6 means, we provide code for ios 6 and ios7 also. In same case also followed here or do some other technic for this. </p>
