- Create a new Objective-C File. Name it “Bar”. Set File Type to “Category”. Set class to “Foo”. Click Next, then Create. Nothing happens.

Yes, I'm one of those old fashioned people who still use Objective-C...
I just hit this same regression myself after updating to Xcode 15.1 (from Xcode 15) today.
It's pretty sad to see such an obvious regression in a minor release. Apple claims Objective-C is still fully supported (I asked about this at WWDC), so there's really no excuse for such an obvious testing miss.
FWIW, selecting Extension also does not work anymore, though I don't know if I ever tried that one before.
Thanks for filing feedback. I need to file a report myself when I get a chance.
