Can't attach popup button to delegate

New project, trying to attach the popup button to a function. I have the popup button’s value populated from a record via an arraycontroller, but if I try to attach the sent action to the delegate, it doesn’t work. Delegate doesn’t highlight at all, nothing.

I’m pretty sure I’m missing something simple here.

Is the .applescript file saved with linefeeds for line breaks?

it’s all in Xcode, so I assume it’s correct in terms of linefeeds.

So you’re control-dragging from the popup and the delegate icon isn’t highlighting?

Is the project using storyboards?

No, unless Xcode snuck them in. I’m not clever enough for those.

Sigh, never mind. Looks like the project was borked. I created a new project, it’s all working correctly.
