Update a Collection - Kotlin SDK

To update a collection of objects in a realm:

1. Query a realm for a collection of objects with realm.query().
2. Open a write transaction with realm.write() or realm.writeBlocking().
3. Update elements of the set of RealmResults returned by the query.

val tadpoles: RealmQuery<Frog> =
    realm.query<Frog>("age > $0", 2)
for (tadpole in tadpoles.find()) {
    realm.write {
        findLatest(tadpole)?.name = tadpole.name + " Jr."
    }
}
