title: thread 1 EXC_BREAKPOINT (code=1, subcode=0x101959bfc) Swift
body: <p>I try to update my project to Swift 3 and my app crash just after launching Xcode display the following message:</p>
  
  <blockquote>
    <p>thread 1 EXC_BREAKPOINT (code=1, subcode=0x101959bfc) </p>
  </blockquote>
  
  <p>here's the line where the problem happened </p>
  
  <pre><code>var list:[PFObject]! = []
             (...)
  let x = list[indexPath.row - 1]
  
  let text:Int = (x["text"] as! NSArray)[0]  as! Int //The line where the error is displayed 
  </code></pre>
  
  <p>The console only said that:</p>
  
  <blockquote>
    <p>(lldb) </p>
  </blockquote>
  
  <p>I've removed all the breakpoints from the breakpoints navigator with no result, the issue happened both on device and on simulator. (I use Xcode 8.2)
  Thanks a lot for your help</p>
