Swift check if core data objects allSatisfy a predicate

Question

I have fetchedResultsController that uses an entity named Convo. I am trying to check if the fetched objects all satisfy a given predicate on tap of a button like this...

    if fetchedResultsController.fetchedObjects?.allSatisfy(){
            print("All objects have been read")
        }else{
            print("All objects have not been read")
        }

But I am unsure how to enter isRead as the allSatisfy() parameter argument. My Convo entity has these attributes

.

I would like to check for isRead .
