Can we get the list or count of the URLs blocked using the Safari web extension content blocking on the iOS app?
There's no supported way for you to get the blocked sites with the APIs currently available. If you'd like us to consider adding the necessary functionality, please file an enhancement request using Feedback Assistant. Once you file the request, please post the FB number here.

No. That would breach the user's privacy. You, as the app developer, do not need to see what sites have been visited, and you don't need to see a count either because you could have a list that includes just pornographic content to block, and you'd know they'd been visiting those sites.
