我正在使用
Xcode 7.2,Swift 2.1.1.我在下面有一个Realm模型对象
class B: Object {
dynamic let lists = List<A>()
}
但Swift编译器给出了一个错误说：
Property cannot be marked as dynamic because its type cannot be represented in Objective-C
我看到Realm的文档说：
Realm model properties need the dynamic var attribute in order for these properties to become accessors for the underlying database data.
There are two exceptions to this: List and RealmOptional properties
cannot be declared as dynamic because generic properties cannot be
represented in the Objective-C runtime,which is used for dynamic
dispatch of dynamic properties,and should always be declared with let
但是现在似乎没有解决这个问题.我错过了什么？
您引用的文档包括以下内容(强调我的)：
List and RealmOptional properties cannot be declared as dynamic because generic properties cannot be represented in the Objective-C runtime,[…],and should always be declared with let.
这意味着您的属性应该如下声明：
let lists = List<A>()
Realm Swift文档最近获得了property declaration cheatsheet,希望能够澄清不同类型声明的要求.
