Currently, we only support RealmAny.asRealmObject<DynamicRealmObject>() for dynamic realms. This makes it problematic to retrieve RealmAny values where the type might be uncertain.

Obviously, the workaround could be to have a second field:

class Person: RealmObject {
  var mixed: RealmAny? = null
  var type: String = "Child"
}

fun test(person: Person) {
  val clazz = when(person.type) {
    "Child" -> Child::class,
    else -> TODO()
  }
  val child: Child = person.mixed!!.asRealmObject(clazz)
  // Do things with the child
}

But maybe it would make more sense to be able to use our dynamic capabilities directly, i.e.:

class Person: RealmObject {
  var mixed: RealmAny? = null
}

fun test(person: Person) {
  val childType: DynamicRealmObject = person.mixed!!.asRealmObject<DynamicRealmObject>().type
  val clazz = when(childType) {
    "Child" -> Child::class,
    else -> TODO()
  }
  val child = person.mixed!!.asRealmObject(clazz)
  // Do things with the child
}

In particular, deleting an object probably doesn't require knowing the type, ie.: MutableRealm.delete(DynamicRealmObject).
