Xcode 8 playground live view doesn't work : <p>In my Swift playground, I entered the following code to test the live view feature: </p>

<pre><code>let view = UIView()

PlaygroundPage.current.liveView = view
</code></pre>

<p>But for some reason the live view doesn't display on the right in the Assistant Editor. Initially I thought that Xcode wasn't finished running the playground. But I waited and waited and it still doesn't show. </p>
