title: Xcode 5, iOS7 and 64bit vs 32bit
body: <p>I have an application that I have in the store and it supports 32bit(iPhone 4+) on iOS 6+</p>
  
  <p>I now also have an iPhone 5S and I'm currently using Xcode five.</p>
  
  <p>I was able to successfully run my app under iOS seven with minimal tweaking, just for a status bar.</p>
  
  <p>I now want to release a version that support iOS seven (For look and feel of tableviews/controls) but also supports iOS six for my current users.</p>
  
  <p>How can I build my up so it's compatible with iOS six and iOS seven?</p>
  
  <p>Do I have to build an iOS six version and a separate binary that I submit separately for iOS seven?</p>
  
  <p>Also I would like to support the <strong>64-bit CPU/architecture in the iPhone 5S</strong>, how can I support this?</p>
  
  <p>Looking in instruments my app is still 32 bit even running on iPhone 5s,</p>
  
  <p>Do I have to build separate iOS six, iOS seven, and iOS seven 64-bit binaries? and submit each version separately to the store?</p>
