title: XCode 5 and iOS 6 and 7
body: <p>I'm working on an iOS app that I wrote with Xcode 4.6 and iOS 6.x. Now that XCode 5 has been released alongside with iOS 7, I wanted to support both iOS 6.x and iOS 7.x by using either XCode 4.6 or XCode 5. What is the best way to approach this?. Can I just toggle between iOS 6.x SDK and iOS 7.x SDK from within XCode 4.6 or do I have to upgrade to XCode 5 to accomplish this?.</p>
  
  <p>Please advise.</p>
