Realm一對多

Question

前些日子，這沒問題，但最近它不起作用。

import UIKit 
import RealmSwift 

class Dog: Object { 

    dynamic var name = "" 
    dynamic var age = 3 

} 

import UIKit 
import RealmSwift 

class People: Object { 

    dynamic var name = "" 
    dynamic var age = 3 
    var dogs = List<Dog>() 

} 

import UIKit 
import RealmSwift 

class ViewController: UIViewController { 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     let dog1 = Dog() 
     dog1.age = 1 
     dog1.name = "旺財" 
     let dog2 = Dog() 
     dog2.age = 3 
     dog2.name = "大黃" 

     let p = People() 
     p.age = 24 
     p.name = "小明" 
     let dogs = List<Dog>() 
     dogs.append(dog1) 
     dogs.append(dog2) 

     let realm = try! Realm() 
     try! realm.write { 

      realm.add(p) 
     } 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 
}

} 

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