Decoding Json in swift - Array but now a dictionary - json

Question

I previously decoded the following response correctly:
GET https://api.spoonacular.com/recipes/findByNutrients?minCarbs=10&maxCarbs=50&number=2
[
{
"calories": 210,
"carbs": "43g",
"fat": "3g",
"id": 90629,
"image": "https://spoonacular.com/recipeImages/90629-312x231.jpg",
"imageType": "jpg",
"protein": "1g",
"title": "Baked Apples in White Wine"
},
{
"calories": 226,
"carbs": "33g",
"fat": "10g",
"id": 284420,
"image": "https://spoonacular.com/recipeImages/284420-312x231.jpg",
"imageType": "jpg",
"protein": "2g",
"title": "Chocolate Silk Pie with Marshmallow Meringue"
}
]
Using this codable model:
struct RecipieAPI: Codable {
var calories : Int
var carbs : String
var fat : String
var id : Int
var image : String
var imageType : String
var protein : String
var title: String
}
However I am now using a different api endpoint with the following response:
GET https://api.spoonacular.com/recipes/complexSearch?query=pasta&maxFat=25&number=2
{
"offset": 0,
"number": 2,
"results": [
{
"id": 716429,
"calories": 584,
"carbs": "84g",
"fat": "20g",
"image": "https://spoonacular.com/recipeImages/716429-312x231.jpg",
"imageType": "jpg",
"protein": "19g",
"title": "Pasta with Garlic, Scallions, Cauliflower & Breadcrumbs"
},
{
"id": 715538,
"calories": 521,
"carbs": "69g",
"fat": "10g",
"image": "https://spoonacular.com/recipeImages/715538-312x231.jpg",
"imageType": "jpg",
"protein": "35g",
"title": "What to make for dinner tonight?? Bruschetta Style Pork & Pasta"
}
],
"totalResults": 86
}
And I am very unsure how I should change my code to get the array inside the dictionary appropriately. Any help would be really really appreciated :)
Note this is in my services class:
AF.request("https://api.spoonacular.com/recipes/complexSearch?apiKey=\(NetworkServices.apiKey)&diet=Whole30&minCarbs=\(minCarbs)&maxCarbs=\(maxCarbs)&number=\(number)", method: .get).responseJSON { (response) in
switch response.result {
case .success(_):
let decoder = JSONDecoder()
if let data = response.data {
do {
let nutrients = try decoder.decode([RecipieAPI].self, from: data)
completionHandler(nutrients, nil)
} catch let error {
completionHandler(nil, error)
}
}
case .failure(let error):
completionHandler(nil, error)
}
}

Answer 1

Add the new root model with the nested key results which you were decoding previously
struct Root: Codable {
var results : [RecipieAPI]
}
struct RecipieAPI: Codable {
var calories : Int?
var carbs : String
var fat : String
var id : Int
var image : String
var imageType : String
var protein : String
var title: String
}
Then
let nutrients = try decoder.decode(Root.self, from: data)
completionHandler(nutrients.results, nil)
