The Apple documentation is pretty good about describing how to determine if two UTIs are equal. See the documentation here:
<https://developer.apple.com/library/content/documentation/FileManagement/Conceptual/understanding_utis/understand_utis.tasks/understand_utis_tasks.html#//apple_ref/doc/uid/TP40001319-CH203-BABHCIAC> Specifically the section titled "Testing for Equality and Conformance."
