问题
I am working in the Playground. I accidentally was using OSX playgrounds instead of iOS Playgrounds, so I opened a new Playground for iOS. When I opened the Playground I immediately got this error:
"The runtime for the selected device is not installed."
This error pops up every time I try to type anything into the playground. This did not happen in the Playgrounds I created that were OSX.
Yes, I turned it off and back on again. :)
I see in this question:
The runtime for selected device is not installed error
that other people are having a similar issue when they are trying to run the simulator.
Has anyone else encountered this issue and is able to provide some insight into this? Thank you!

"Bare" playground files are not working very well. Here's a workaround:
Make a new iOS project from one of the templates, and build it. Now add a new file to that project and make it an iOS playground. Now the playground will work.
