RealmConfiguration Builder needs Realmobjects during create

At the moment I use the following code to create a Realm DB in my Android Environment.
“RealmConfiguration.Builder(setOf(SchemeContacts::class))”
But on my previous project I could do this “RealmConfiguration.Builder()” without giving up the object before hand.

SInce when is this changed? I couldnt find this change in the changelog.

Is there a way to get this to work without to give beforehand the objects?
