Swift 3/JSON - How to capture List of objects inside an object?

Question

How do I access a list of objects within another list of objects?
I can capture these objects peacefully, but I’m having trouble capturing objects within this list.
This is my JSON:

In this case I want to have access to the values that are within "NOTES" and "MISSING" but I’m not having much success in this...
Follows my code:

 for item in resultado!{

    let newDisc = DisciplinasML()

    newDisc.codDisciplina = item["COD_DISCIPLINA"]! as? String
    newDisc.desDisciplina = item["DES_DISCIPLINA"]! as? String
    newDisc.desPeriodo = item["DES_PERIODO"]! as? String
    newDisc.medDisciplina = item["MEDIA_DISCIPLINA"]! as? String
    newDisc.nomProfessor = item["NOM_PESSOA_PROF"]! as? String
    newDisc.perFaltas = item["PERCENTUAL_AULAS"]! as? String

       //Eu acho que não seja assim que se capture o valor
       for nota in (item["NOTAS"]! as! NSArray){

           //nota has no subscription members     
           print(nota["COD_AVALIACAO"] as String)

       }
        //Adiciono os itens na lista
        self.listDisciplinasWS.append(newDisc)
 }

Any hint?
I appreciate all your help

Instead of using NSArray try to use the native Swift types by using the NSArray compiler cannot infer that the array contains dictionaries within it.

for item in resultado!{

    let newDisc = DisciplinasML()

    newDisc.codDisciplina = item["COD_DISCIPLINA"]! as? String
    newDisc.desDisciplina = item["DES_DISCIPLINA"]! as? String
    newDisc.desPeriodo = item["DES_PERIODO"]! as? String
    newDisc.medDisciplina = item["MEDIA_DISCIPLINA"]! as? String
    newDisc.nomProfessor = item["NOM_PESSOA_PROF"]! as? String
    newDisc.perFaltas = item["PERCENTUAL_AULAS"]! as? String

    // Modificação ocorre nessa parte do código
    for nota in (item["NOTAS"]! as! [[String:Any]]){

       //nota has no subscription members     
       print(nota["COD_AVALIACAO"] as! String)

    }

    self.listDisciplinasWS.append(newDisc)
}
