title: Do we need to compile iOS App for both "armv7" and "arm64" if my deployment target is 8.0?
body: <p>My App supports from iOS8.0 and above. And I know that from iOS7 onwards its arm64 bit architecture. In that case do we need to compile the binary for both "armv7" and "arm64" slices?</p>
  
  <p>If I compile for arm64 alone, I can reduce my App size. Is it a right way ?</p>
  
  <p>Please help.</p>
