I'm trying to create a simple macOS Playground with a couple buttons in a view to trigger some code. The Xcode 9 template works, and shows the live view with "Hello World!" displayed. But after editing the Storyboard, my button doesn't show up. I tried modifying the text of the existing label, and that change doesn't show up either.
Google is useless because a) results are old and b) results are for iOS.
Like so much stuff from Apple these days, this seems broken. At best it's extremely counterintuitive.
Any suggetsions on how to get past this?
Thanks!
