Xcode Playgrounds Showing "Empty Image"

Question

I downloaded Xcode 9.2 today and, admittedly I haven't attempted to do so in a while, I tried to render a view in the playground and kept getting a "empty image" in the sidebar.

Anyone know what's up?

Answer 1

I had the same issue, click the assistant editor to view the UI.

In the picture below, it's the icon highlighted in blue.
