title: Xcode C++ Vectors: Implicit instantiation of undefined template
body: <p>I ran this code on a different IDE and it was successful. For some reason I get the above error message on Xcode. I assume I'm missing a header of some kind, but I'm not sure which one.</p>
  <pre><code>#include &lt;iostream&gt;
  #include &lt;limits&gt;
  #include &lt;string&gt;
  #include &lt;vector&gt;
  
  int main() {
      vector&lt;string&gt; listRestaurants;  // error: Implicit instantiation of undefined template
      return 0;
  }
  </code></pre>
