I grabbed the old Spotlight importer xctemplate from Xcode 8, installed it in Xcode 16.4 and surprisingly it seems to generate a valid .mdimporter package, but I would MUCH prefer to have a more modern (preferrably Swift!) skeleton to work with if possible. We have no real idea as to when CSImportExtension will be fixed in macOS, so I'd really like to have a way to integrate with Spotlight in the interim. Also would be nice for those of us that still have to support older versions of the OS

Nice!

Fair point. I hadn't tried with binary targets so was unaware of their status. Apologies.

Same issue here with Xcode 14 beta 6 - raised FB11397938

Yup. Just ran into the same issue here in my own code. The outputImage function in the custom filter never gets called if assigned to NSView backgroundFilters/contentFilters or any layer filter(s), whereas assigning (eg.) CIFilter.stripesGenerator() works fine. Highly frustrating.
