title: iTunes connect: confused on Bundle ID
body: <p>I have been excited to try to add for the FIRST time a new App on iTunes Connect to TEST my GAMEKIT features.</p>
  
  <p>I have read <a href="http://developer.apple.com/library/ios/#qa/qa1713/_index.html" rel="noreferrer">this</a> technical note  and I am getting confused because I had already a boundle id for my App that I created when I started developing it (that's my current bundle id with which I created the current provisioning and testing profiles: hello-*).</p>
  
  <p><img src="https://i.stack.imgur.com/AArbw.png" alt="enter image description here"></p>
  
  <p>In order to use GameKit and InApp Purchase should I create a new Bundle Id?</p>
  
  <p>I am confused because:</p>
  
  <ul>
  <li>I don't know if the current Bundle Id is valid (in respect to the technical note linked above)</li>
  <li>I don't know if hte Bundle Id influences the things that I can ADD in the App later (E.g. in App Purchase, GameKit, ...)</li>
  <li>If I create a new App with a name (say: HelloApple) but with a bundle Id with wildcard (Say: hello-*) will I be able to add a new App with the same name but a different bundle Id in a later stage? This indeed before publishing ANY of the two Apps.</li>
  <li>I don't fully understand why there is a choice between using or not using a wildcard; in other words, if a non wildcard bundle id is needed to use in App purchase and GameKit why should a developer want to use a wildcard App Id?</li>
  </ul>
  
  <p>Any help will be appreciated, in particular I need to solve my first issue: which bundle Id should I use in ordert to use GameKit and InAppPurchase?</p>
