let openingHours = List<ShopHourRealm>()

import RealmSwift

// Dog model
class Dog: Object {
    @objc dynamic var name = ""
    @objc dynamic var owner: Person? // Properties can be optional
}

// Person model
class Person: Object {
    @objc dynamic var name = ""
    @objc dynamic var birthdate = Date(timeIntervalSince1970: 1)
    let dogs = List<Dog>()
}
