Pulling Data from JSON Array to make 3 different Arrays

Question

I'm trying to make three arrays based on the JSON Data that I'm pulling from my restaurant. I want to have an array of Entre, Main, & Dessert that will display in a tableView Object. This is the code I'm using to pull in data:

func loadMeals() {
    Helpers.showActivityIndicator(activityIndicator, view)

    if let restaurantId = restaurant?.id {
        APIManager.shared.getMeals(restaurantId: restaurantId, completionHandler: { (json) in
            if json != nil {
                self.meals = []

                if let tempMeals = json["meals"].array {
                    for item in tempMeals {
                        let meal = Meal(json: item)
                        self.meals.append(meal)
                    }

                    self.tableView.reloadData()
                    Helpers.hideActivityIndicator(self.activityIndicator)
                }
            }
        })
    }
}

Item prints out:

items {
  "name" : "Spinach Artichoke",
  "course" : "entres",
  "short_description" : "savory",
  "id" : 20,
  "image" : "http:\/\/localhost:8000\/media\/product_images\/artichoke.jpg",
  "usage" : "homestyle",
  "sizes" : [
    {
      "size" : 3,
      "id" : 24,
      "product_id" : 20,
      "price" : 55.899999999999999
    },
    {
      "size" : 4,
      "id" : 25,
      "product_id" : 20,
      "price" : 78
    },
    {
      "size" : 5,
      "id" : 26,
      "product_id" : 20,
      "price" : 125
    }
  ]
}
items {
  "name" : "Pizza",
  "course" : "main",
  "short_description" : "Melty cheese",
  "id" : 19,
  "image" : "http:\/\/localhost:8000\/media\/product_images\/pizza.jpg",
  "usage" : "top",
  "sizes" : [
    {
      "size" : 6,
      "id" : 23,
      "product_id" : 19,
      "price" : 75.989999999999995
    }
  ]
}
items {
  "name" : "Chocolate Mousee Devil's cake",
  "course" : "dessert",
  "short_description" : "Sweet And Smooth",
  "id" : 18,
  "image" : "http:\/\/localhost:8000\/media\/product_images\/Devils_cake.jpg",
  "usage" : "sweets",
  "sizes" : [
    {
      "size" : 2,
      "id" : 20,
      "product_id" : 18,
      "price" : 50
    },
    {
      "size" : 3,
      "id" : 21,
      "product_id" : 18,
      "price" : 120
    },
    {
      "size" : 4,
      "id" : 22,
      "product_id" : 18,
      "price" : 376
    }
  ]
}

I'm trying to figure out how to create the arrays by pulling the data from this function. Any help would be appreciated.

What would you like your array to be exactly like? Can you give a format example? — Attersson

Just You need to group By course

meals Array will be [[String:Any]] Key will be course Any will be Array of course items

  func loadMeals() {
         Helpers.showActivityIndicator(activityIndicator, view)

          if let restaurantId = restaurant?.id {
                    APIManager.shared.getMeals(restaurantId: restaurantId, completionHandler: { (json) in
                        if json != nil {
                            self.meals = []

                            if let tempMeals = json["meals"].array {
                               self.meals =  Dictionary(grouping: tempMeals, by: { $0["course"] as! String })
                                self.tableView.reloadData()
                                Helpers.hideActivityIndicator(self.activityIndicator)
                            }
                        }
                    })
                }
            }

OutPut Console:

["Main": [["name": Chocolate Mousee Devil's cake, "course": Main, "short_description": Sweet And Smooth, "id": 18, "image": http://localhost:8000/media/product_images/Devils_cake.jpg, "usage": sweets, "sizes": <__NSArrayI 0x60c0002456a0>(

I intended to use separators in the tableview to announce the specific kind of meal. Is it possible to do that if the array shows all items?

Abdelahad Darwish Over a year ago

I split your data to be key and items do arrange your code to section table by course key

I'm trying this now but, "jsonDictionary" doesnt seem to be a valid key. I've imported swiftyJson but, it still doesn't seem to work

Sorry jsonDicyionary is my own I fix it check update

Doing Things Occasionally Over a year ago
