Aktuelle Response = [ "Unterrichtsplanung": [ "name": "test" "Tage": 2, "Woche": 1, "Stunden": 1, "lessonAssignment": [HSP.LessonAssignment, HSP.LessonAssignment] "lessonNote": []]]

Erwartete Antwort = ["lessonPlan": ["name": "test", "tage": 2, "wochen": 1, "stunden": 1, "lektionAssignment": [["titel"] : "1 einen gewissen Wert", "Kategorie": "some value", "Woche": 1, "Tag": 2]] "lessonNote": []]]

Anstelle des LessinAssignment Objekt I möchte die tatsächlichen Werte hinzufügen, die Array ist. Irgendein Hinweis, wie man das löst. Ich weiß, dass ich mehr Logik innerhalb der toDictionary Methode hinzufügen muss und basierend auf dem Schlüssel "lectionAssignment" muss ich jedes Array erhalten und den Wert im Schlüssel als finales Array hinzufügen.

Answer 1

Von meinem Kommentar, so etwas wie dieses:

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