Fast, Swifty data storage

// Define your models like regular Swift classes
class Dog: Object {
    @Persisted var name: String
    @Persisted var age: Int
}
class Person: Object {
    @Persisted(primaryKey: true) var _id: String
    @Persisted var name: String
    @Persisted var age: Int
    // Create relationships by pointing an Object field to another Class
    @Persisted var dogs: List<Dog>;
}
// Use them like regular Swift objects
let dog = Dog()
dog.name = "Rex"
dog.age = 1
print("name of dog: (dog.name)")

// Get the default Realm
let realm = try! Realm()
// Persist your data easily with a write transaction 
try! realm.write {
    realm.add(dog)

// Open the default realm.
let realm = try! Realm()
var token: NotificationToken?

let dog = Dog()
dog.name = "Max"

// Create a dog in the realm.
try! realm.write {
    realm.add(dog)
}

//  Set up the listener & observe object notifications.
token = dog.observe { change in
    switch change {
    case .change(let properties):
        for property in properties {
            print("Property '(property.name)' changed to '(property.newValue!)'");
        }
    case .error(let error):
        print("An error occurred: (error)")
    case .deleted:
        print("The object was deleted.")
    }
}

// Update the dog's name to see the effect.
try! realm.write {
