Marcin Krzyzanowskiintroduced in macOS 12 "CSImportExtension was never fully implemented on macOS"
but remember to fill bug reports everyone, it helps
Darren@krzyzanowskim is annoying that there used to be a MDImporter Xcode template which was removed in Xcode 9 for a template based on CSImportExtension which (as was confirmed today) has never worked on macOS.
Had to download Xcode 8 and extract the xctemplate files (surprisingly they still work in Xcode 16) because there’s definitely magic in them thar hills with MDImporter.
At least it’s now confirmed *by Apple* that it’s never worked.
@dagronf share that template, I may want to try it too
@krzyzanowskim I've uploaded it to dropbox at the following link.
The 'Spotlight Importer.xctemplate' folder needs to go into "Xcode.app/Contents/Developer/Library/Xcode/Templates/Project Templates/Base"
@krzyzanowskim There's also a basic working importer for playgrounds here
@dagronf thank you!
