{     “green shirt": [         {             "id": "740",             "name": “nice green shirt",             "quantity": "0",             "make": "",             "model": "",             "price": “15.00",             "size": "xxs",             "sku": null,             "image": "https:\/\/google.com\/green_shirt.jpg",             "new_record": false,             "category_name": "",             "bar_code": "",         },         {             "id": "743",             "name": "green shirt",             "quantity": “68",             "make": "",             "model": "",             "price": “20.00",             "size": "xs",             "sku": null,             "image": "https:\/\/google.com\/green_shirt.jpg",             "new_record": false,             "category_name": "",             "bar_code": "",         }     ],     “dark blue jeans": [         {             "id": "1588",             "name": "dark blue jeans",             "quantity": "0",             "make": "",             "model": "",             "price": "0.00",             "size": “s",             "sku": null,             "image": "https:\/\/google.com\/dark_blue_jeans.jpg",             "new_record": false,             "category_name": "",             "bar_code": "",             "category": null         },         {             "id": "1559",             "name": "dark blue jeans",             "quantity": "4",             "make": "",             "model": "",             "price": "0.00",             "size": “xl",             "sku": null,             "image": "https:\/\/google.com\/dark_blue_jeans.jpg",             "new_record": false,             "category_name": "",             "bar_code": "",             "category": null         }     ],     “white belt": [         {             "id": "1536",             "name": "white belt",             "quantity": "37",             "make": "",             "model": "",             "price": "0.00",             "size": "one size",             "sku": null,             "image": "https:\/\/google.com\/white_belt.jpg",             "new_record": false,             "category_name": "",             "bar_code": "",             "category": null         }     ] } 

class should take json response

public class inventory {     public var products = [product]()      public init(type: product.type, data:[[string:anyobject]]) {         productdata in data {             products.append(type(data: productdata))         }     } } 

product class

public class product {     public var data:[string:anyobject]      required public init(data: [string:anyobject]) {         self.data = data     } } 

main product class

class mainproduct : product {     var id:string? {         return data["id"] as? string     }      var name:string {         return data["model"] as! string     }      var sizes:[string:int] {         if let items = data["quantities"] as? [string:int] {             return items         } else {             return [string:int]()         }     }      var upc :string? {         return data["upc"] as? string     }      var price:double {         if let price = data["price"] as? double {             return price         } else if let price = data["price"] as? nsstring {             return price.doublevalue         } else {             fatalerror("did not price")         }     } } 

you missing code needed load json file , parse it. also, json have posted has illegal characters choke parser. e.g.: { “green shirt": [ first quote curly quote. first, need clean of these up.

then save json along source files in, "data.json". if did that, parse json this:

var error: nserror? = nil let path = nsbundle.mainbundle().pathforresource("data", oftype: "json") let jsondata = nsdata(contentsoffile: path!, options: .datareadingmappedifsafe, error: &error) let jsonresult = nsjsonserialization.jsonobjectwithdata(jsondata!, options: nsjsonreadingoptions.allowfragments, error: &error) as! nsdictionary

then pull product data parsed json dictionary product objects.
