title: Bundle ID and SKU number
body: <p>I'm adding an iOS App to iTunes Connect, but are confused regarding the two values <code>Bundle ID</code> and <code>SKU Number</code> which I have to chose for my App. </p>
  
  <ol>
  <li>When I create a new iOS project in Xcode, lets say "MyProject", it's iOS Application Identifier would be com.mycompany.MyProject. Should the iOS Application Identifier be all lower case or what are the "guidelines"? E.g. com.MyCompany.MyApplication, com.mycompany.MyApplication or com.mycompany.myapplication? What are the guidelines regarding this?</li>
  <li>Should this iOS Application ID in Xcode be equal to the Bundle ID in <code>iTunes Connect</code> and <code>iOS Provisioning Portal</code>?</li>
  <li>Could someone give me an example of, what the SKU Number could look like?</li>
  </ol>
