模型嵌套一个模型json转模型后，属性模型一直为空？

//b必须
class KIStudent: HandyJSON {
var type : String?
var iconName : KIStudent?
}

class Parent: HandyJSON {
var name : String?
var student : KIStudent?
}

let dictionary = ["name":"zd"."student": ["type":"1","iconName":"oppo"]]

if let parent = Parent.deserialize(from: dictionary) {
// …
parent.student //打印一直是nil

}

Start by reproducing the Swift snippet with Parent.deserialize(from:) and inspect how HandyJSON handles the nested student property. Trace the nested-model deserialization path and verify the result by checking that parent.student is populated with the supplied type and iconName values.
