title: Many leaks showing in Instruments caused by Array and Dictionary
body: <p>I was testing my app using Instruments checking for any leaks and to my surprise it's showing many leaks caused mainly by:</p>
  
  <pre><code>_ContiguousArrayStorage&lt;String&gt;
  _ContiguousArrayStorage&lt;Int&gt;
  _ContiguousArrayStorage&lt;NSLayoutConstraint&gt;
  
  _NativeDictionaryStorageOwner&lt;Int, CGFloat&gt;
  _NativeDictionaryStorageOwner&lt;String, AnyObject&gt;
  </code></pre>
  
  <p>The tests are done on an iPhone 5s, iPhone 6s and iPad Pro. All of the devices are running iOS 10.</p>
