Per the docs, NSImage.imageTypes returns a list UTI's, something like below:

com.adobe.pdf
com.apple.pict
com.adobe.encapsulated-postscript
public.jpeg
public.png
com.compuserve.gif
com.canon.tif-raw-image
...

What I need is get file extensions of a UTI. For example, public.jpeg picture file may have several file extensions, say .jpg,.jpeg,.jfif.

Does Cocoa provide any API to query for this information?

Yes! That's just what I need.

if let ut = UTType.types(tag: "jpeg", tagClass: .filenameExtension, conformingTo: nil).first {
    print(ut.tags[.filenameExtension])
}
