title: Running App with Xcode takes long time to launch
body: <p>Here is my problem :</p>
  
  <p>When I'm testing my App using Xcode, my app freeze (and Xcode too) for a long time after displaying the Launch Image. </p>
  
  <p>But when testing my app without Xcode, it runs normally.</p>
  
  <p>I've noticed something : in the console of my device (Organizer / Devices / MyDevice / Console), when I launch the app from Xcode, some strange logs are displayed :</p>
  
  <pre><code>&lt;Error&gt;: Max open files: 125
  </code></pre>
  
  <p>is written like 20 times</p>
  
  <p>and also : </p>
  
  <pre><code>&lt;Warning&gt;: CoreAnimation: updates deferred for too long
  &lt;Warning&gt;: CoreAnimation: timed out fence 1954b
  &lt;Warning&gt;: CoreAnimation: failed to receive fence reply: 10004003
  </code></pre>
  
  <p>It still stuck on those 3 last lines for a while, and then carry on the execution.</p>
  
  <p>What is happening? </p>
