swift3 parsing with model issue - ios

Question

Hello I am trying to parse through this json file: http://pastebin.com/TCdkJnvZ
Here is the class I made of the information I want to parse out:
public class Recipe: NSObject {
var recipeID : NSNumber?
var categoryName : String?
var ingredients : [Int : Ingredients]?
var nutrition : [Nutrition]?
var imageName : String?
var instructions : [Int : String]?
}
class Ingredients : NSObject {
var id : NSNumber?
var name : String?
var quantity: NSNumber?
var unit : String?
}
class Nutrition : NSObject {
var serving : String?
var calories : NSNumber?
var fat : String?
var carbs : NSNumber?
}
This image is the current issue.. I am really not sure what I am doing wrong here.. so if I can get any help on fixing my logic/issue it would be appreciated.
func parseToJSON(data: Any) {
// add meals to here
var recipes : [Recipe]
// single meals here
var meals : Recipe
do {
if let json = try JSONSerialization.jsonObject(with: data as! Data) as? [String: Any],
meals.recipeID == json["recipeID"] as! NSNumber? ,
meals.imageName == json["ImageURL"] as! String?,
//meals.instructions == meals.parseInstructions(instructions: (json["Instructions"] as! String)),
meals.categoryName == "Meals" ,
let ingredients = json["Ingredients"] as! [[String: Any]]? {
for items in ingredients {
var i : Int = 0
var groceryItems : Ingredients
groceryItems.id = items["IngredientID"] as? NSNumber
groceryItems.name = items["Name"] as? String
groceryItems.quantity = items["Quantity"] as? NSNumber
groceryItems.unit = items["Unit"] as? String
meals.ingredients?[i] = groceryItems
}
};
let nutritionInfo = json["NutritionInfo"] as! [[String: Any]]? {
for items in nutritionInfo {
var nutrition : Nutrition
nutrition.serving = items["SingularYieldUnit"] as? String
nutrition.calories = items["TotalCalories"] as? NSNumber
nutrition.fat = items["TotalFat"] as? String
nutrition.carbs = items["TotalCarbs"] as NSNumber
meals.nutrition = nutrition
}
};
}
catch{
}
}

It looks like you have a variety of syntax errors, but the compiler can only show one issue at a time. I've cleaned up the code slightly for you, which should push you in the right direction. I can't completely fix it because I don't know what your exact intentions are.
Here is the updated parseToJSON function:
func parseToJSON(data: Any) {
let meals = Recipe()
do {
if let json = try JSONSerialization.jsonObject(with: data as! Data) as? [String: Any] {
meals.recipeID == json["recipeID"] as! NSNumber?
meals.imageName == json["ImageURL"] as! String?
//meals.instructions == meals.parseInstructions(instructions: (json["Instructions"] as! String)),
meals.categoryName == "Meals"
if let ingredients = json["Ingredients"] as! [[String: Any]]? {
for items in ingredients {
let groceryItems = Ingredients()
groceryItems.id = items["IngredientID"] as? NSNumber
groceryItems.name = items["Name"] as? String
groceryItems.quantity = items["Quantity"] as? NSNumber
groceryItems.unit = items["Unit"] as? String
meals.ingredients?.append(groceryItems)
}
}
if let nutritionInfo = json["NutritionInfo"] as! [[String: Any]]? {
for items in nutritionInfo {
let nutrition = Nutrition()
nutrition.serving = items["SingularYieldUnit"] as? String
nutrition.calories = items["TotalCalories"] as? NSNumber
nutrition.fat = items["TotalFat"] as? String
nutrition.carbs = items["TotalCarbs"] as? NSNumber
meals.nutrition?.append(nutrition)
}
}
}
}
catch{
}
}
I also changed the Recipe object's ingredients property to:
var ingredients : [Ingredients]?
The main issue was that a lot of your code was inside of an if let expression and your indentation was off so you couldn't as easily tell.
