I use the predicate below as NSExtensionActivationRule for my Share Extension. It shows my extension in the share sheet if the host app provides a public.url OR plain.text.

My question: is there a way to evaluate the URL to decide if my extension should be visible in the share sheet? For example, I would only like to show it if the url matches "https://mydomain.com". I don't think this can be done, but want to be sure.

SUBQUERY (

extensionItems,

$extensionItem,

SUBQUERY (

$extensionItem.attachments,

$attachment,

ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.url"

).@count == 1

it should be possible by testing $attachment with an AND condition against your pattern.

You should be able to use any of ==, LIKE or MATCHES in the test.

The rest is left for you to work out. Maybe you could write a small test app to create and run some predicates to see how this would work?

8 Years later this has not been solved right? I'm also currently looking at this issue and can't figure out how to evaluate the incoming attachments value. Any progress here?
