You can’t exclude your own share extension from your application’s activity controllers

It makes sense that you can’t specifically exclude a specific share extension from an activity view controller. We wouldn’t want Instagram doing something like preventing sharing to Twitter, would we?

But the one extension that you should be able to remove from your own app’s activity view controllers is your own extension. It’s silly to be able to share to Tumblr from within Tumblr. I mean, it works. It’s OK, I guess. But it’s weird.

Workaround

None so far. We tried configuring our activity controllers with an activity item with a custom UTI, and then specifically giving our share extension a predicate that would cause it to not show up when said UTI was present, but it had unintended side effects, which brings us to the next issue…
