Thanks. I don't think I'll file a bug report since this hasn't changed in 6 years. Tried the newly-signed duplicate Automator app and it seems to work for my purposes. Before this I just liberally logged variables, etc. and read the results in Console (after some time trying to find things there), i.e. http://macosautomation.com/automator/xcode-swift-template/index.html

And today it works for me again.

Never mind. Seems to work fine. Thanks.
