Thank you. That did the work, i ended up removing this part too from the CachedFriend entity:

public var usersArray: [CachedUser] {
        let set = user as? Set<CachedUser> ?? []

        return set.sorted {
            $0.wrappedName < $1.wrappedName
        }
    }

Since i was not using that anywhere, the list that shows the friends uses the friendsArray from the CachedUser entity, where i copied the code that looks like the one above and tried to do the same thing for this usersArray.

Thank you once again.
