I could easily do this by adding conformance to a new protocol called Codable.

我可以轻松做到这点，只要在一个叫做 Codable 的新协议里添加一致性就好了。

So I will start once again by declaring conformance to a new delegate protocol, UICollectionView drop delegate.

我将从再次声明遵守新的委托协议开始，也就是 UICollectionView 放置委托。

And if the properties of this type have types that also conform to Codable, this is literally all the code I need to write because the conformance to this protocol is synthesized by the compiler.

如果这个类型的属性具有与 Codable 一致的类型，这就是所有我需要写的代码了，因为与这个协议的一致性已经被编译程序合成了。
