Delete Multiple Objects - Kotlin SDK

To delete multiple objects from a realm at the same time:

1. Open a write transaction with realm.write() or realm.writeBlocking().

2. Query the transaction's mutable realm for the objects you want to delete with realm.query(). Specify the object type as a type parameter passed to query(). Filter the set of returned objects by specifying a query.

3. Delete the set of RealmResults returned by the query with realmResults.delete().

realm.write {
    // fetch 7 frogs of the bullfrog species from the realm
    val frogs: RealmResults<Frog> =
        this.query<Frog>("species == 'bullfrog' LIMIT(7)").find()
    // call delete on the results of a query to delete those objects permanently
    delete(frogs)
}
