Hello, I need help, I do not know how to do a JsonArray in swift 3, the only thing I've achieved is to do this:

{ "Etiqueta":"valor", "":"", "":"" }

and what I need to do is this:

[
   {
      "Etiqueta":"valor",
      "Etiqueta":"valor",
      "Etiqueta":"valor"
   },
   {
      "Etiqueta":"valor",
      "Etiqueta":"valor",
      "Etiqueta":"valor"
   }
]

the code I use to create the json is this:

    var json = [String : AnyObject]()
    var arrayFinish = [String: AnyObject]()

    json["idProducto"] = String(celda) as AnyObject
    json["comentario"] = tfComentario.text! as AnyObject
    json["TipoUnidad"] = pickerselected as String as AnyObject
    json["Cantidad"] = cantidad as String as AnyObject
    json["Medida"] = medidas as String as AnyObject
    json["telefono"] = telefono as String as AnyObject

    arrayFinish["productos"]?.add(json)

and the only thing I get is [:] like this is shown in log

You are not adding it well, you must give the array already complete.

    var arrayProductos = [[String : AnyObject]]()
    var json = [String : AnyObject]()
    var arrayFinish = [String: AnyObject]()

    json["idProducto"] = String(celda) as AnyObject
    json["comentario"] = tfComentario.text! as AnyObject
    json["TipoUnidad"] = pickerselected as String as AnyObject
    json["Cantidad"] = cantidad as String as AnyObject
    json["Medida"] = medidas as String as AnyObject
    json["telefono"] = telefono as String as AnyObject

    arrayProductos.append(json)

    arrayFinish["productos"] = arrayProductos as AnyObject

And although you're calling it json, you're actually working with dictionaries. If you would like to send it to an API you should use JSONSerialization
