电流响应= [ “lessonPlan”：[ “名称”： “测试” ， “天”：2 “周”：1， “小时”：1， “lessonAssignment”：[HSP.LessonAssignment， HSP.LessonAssignment]， “lessonNote”：[]]]

= [“lessonPlan”：[“name”：“test”，“days”：2， “weeks”：1，“hours”：1，“lessonAssignment”：[[“title” ：“some value 1”，“category”：“some value”，“week”：1，“day”：2]]，“lessonNote”：[]]]

而不是LessinAssignment对象I想添加数组的实际值。任何线索如何解决这个问题。我知道我必须在toDictionary方法中添加更多的逻辑，并且基于“lessonAssignment”键，我必须获取每个数组并将键值添加为最终数组。

从我的意见，这样的事情：

assignments.map({ 
    (value: HSP.LessonAssignment) -> NSDictionary in 
    return value.toDictionary() 
})
