Current Response = ["lessonPlan": ["name": "test", "days": 2, "weeks": 1,
"hours": 1, "lessonAssignment": [HSP.LessonAssignment,
HSP.LessonAssignment], "lessonNote": []]]
Expected Response = ["lessonPlan": ["name": "test", "days": 2,
"weeks": 1, "hours": 1, "lessonAssignment": [["title" : "some value 1", "category" : "some value", "week" : 1, "day" : 2]], "lessonNote": []]]
Instead of the LessinAssignment Object I would like to add the actual values which is array. Any clue how to resolve this. I know i have to add some more logic inside the toDictionary method and based on the key "lessonAssignment" I have to get each array and add the value in the key as final Array.

Answer 1

From my comment, something like this:
assignments.map({
(value: HSP.LessonAssignment) -> NSDictionary in
return value.toDictionary()
})
