title: Printing/Debugging libc++ STL with Xcode/LLDB
body: <p>I'm trying to use LLDB within Xcode 8 to debug very basic STL. I used to be able to print a vector like this:</p>
  
  <pre><code>p myvector[0]
  </code></pre>
  
  <p>to see whatever was in the first vector index. Now when I do that, I get this error:</p>
  
  <pre><code>error: Couldn't lookup symbols:
    __ZNSt3__16vectorI9my_classNS_9allocatorIS1_EEEixEm
  </code></pre>
  
  <p>Instead, I have to type this:</p>
  
  <pre><code>p myvector.__begin_[0]
  </code></pre>
  
  <p>in order to get any output.</p>
  
  <p>I tried importing the libcxx.py and unordered_multi.py scripts from the LLDB svn repository but that doesn't seem to change anything.</p>
  
  <p>Has anyone been able to get any useful output from LLDB with libc++?</p>
