Question

我有两个班级：公司和员工。两者都继承了Realm Object 类。

class Company:Object {
    var name:String = ""
    var employee:Employee?

    override static func primaryKey() -> String? {
       return "name"
   }
}

class Employee:Object {
   var name:String = ""
   var age:Int = 0

   override static func primaryKey() -> String? {
      return "name"
   }
}

填充对象

    var emp = Employee()
    emp.name = "Sachin"
    emp.age = 35

    var comp = Company()
    comp.name = "BCCI"

    comp.employee = emp

    println("Before: \(comp.employee)")

    var realm = Realm()
    realm.write {
        println("Before Add: \(comp.employee)")
        realm.add(comp, update: true)
        println("In Block: \(comp.employee)")
    }

    println("After: \(comp.employee)")

结果：

之前：员工{       name = Sachin;       年龄= 35岁;       }
      之前添加：员工{       name = Sachin;       年龄= 35岁;       }
      区块：零       之后：零

问题： 在realm.add()操作之后，为什么公司的员工财产对象为零？有什么想法吗？

对于所有Realm Swift属性（ToString()除外），您需要将属性声明为List。将模型定义更改为以下内容应该有所帮助！

dynamic
