Exported UTI for package/bundle
bundle, cocoa, macos, uti
Solution
Trial-and-error findings:
Is this considered a proprietary format that needs to be exported via Exported UTIs (`UTExportedTypeDeclarations`)?
Yes. While I couldn't find any explicit mention of this in the documentation, exporting the type was necessary for Finder to treat the directories as packages.
- Conforms To (`UTTypeConformsTo`)
`com.apple.package` (source)
- Mime Types (`public.mime-type`)
Empty. Directories don't have a Mime Type?
- Pboard Types (`com.apple.nspboard-type`)
Empty. Pboard Types are deprecated?
- OS Types (`com.apple.ostype`)
No clue.
Finally, does the Exported UTI identifier (`UTTypeIdentifier`) need to be the same value than the Document Type identifier (`LSItemContentTypes`)?
Yes, but I couldn't find any explicit mention of this in the documentation.
Problem
My Cocoa document-based app opens and writes custom packages/bundles. Is this considered a proprietary format that needs to be exported via Exported UTIs (`UTExportedTypeDeclarations`)? If so, what should be the values for: - Conforms To (`UTTypeConformsTo`) - Mime Types (`public.mime-type`) - Pboard Types (`com.apple.nspboard-type`) - OS Types (`com.apple.ostype`) Finally, does the Exported UTI identifier (`UTTypeIdentifier`) need to be the same value than the Document Type identifier (`LSItemContentTypes`)?
