Realm - Swift存储协议类型

Question

I have the following structure:

class Entity : Object {
    dynamic var Id = 0
    dynamic var Title = ""
    dynamic var Subtitle = ""
    var atttribute : MyProtocol?

}

Is there a way of storing something in attribute? Today is returning nil. If I add dynamic it returns the error:

Property cannot be marked dynamic because its type cannot be represented in Objective-C

Is there any way to store properties that conform to a Protocol as that?

不，Realm属性是单态的，Realm需要知道在初始化时将链接到的具体对象类型是什么。
