title: How to access the model's description in CoreML?
body: <p>I have a CoreML model and I've added information to the model using coremltools:</p>
  <pre><code>model.author = 'Vincent Garcia'
  model.license = 'BSD'
  model.short_description = 'The model is doing something.'
  </code></pre>
  <p>Is there a way to access this information from Swift?</p>
  <p>On Apple's documentation, it's written:</p>
  <blockquote>
  <p>Inspect your model’s metadata and MLFeatureDescription instances
  through modelDescription.</p>
  </blockquote>
  <p>I tried this:</p>
  <pre class="lang-swift prettyprint-override"><code>let model = try! MyModel(configuration: MLModelConfiguration())
  let desc = model.modelDescription
  </code></pre>
  <p>but I got the following error:</p>
  <blockquote>
  <p>Value of type 'MyModel' has no member 'modelDescription'</p>
  </blockquote>
  <p>It seems that I'm not using the documentation properly.
  Thanks for your help!</p>
