title: Replicate iOS App Updating procedure from App store in Xcode
body: <p>I removed coreData in my app and use SQLite now. I need to create a new DB after the user updates their app.  I tested by installing the old version in App Store, and installing a new version from Xcode (without deletion). 
  But how do I emulate the updating procedure just like updating from App Store? Can I do this emulation when running the project from Xcode?</p>
  
  <p>For example, version 1.1.1 is on App Store.
  First, I installed this version from App Store onto my phone.
  Normally, the user will update next version from App store, right? 
  But if I install 1.1.2 from Xcode, will this result be the same as updating from the App Store?</p>
