UniformTypeIdentifiers identifies file formats and data types on Apple platforms through UTType values. Apps declare, query, and match content types for documents, the pasteboard, and file handling.

The 27 SDK adds 3 APIs with no deprecations or removals. New entries include a UTType initializer and a UTType.markdown type constant for Markdown content.
