Parse Using Swifty JSON - ios

Question

My JSON is like:
{
"status": 1,
"msg": "Category Product List",
"product_data": [{
"product_id": "49",
"image": "http://192.168.1.78/Linkon/site/pub/static/frontend/Linkon/default/en_US/Magento_Catalog/images/product/placeholder/image.jpg",
"shopName": "putin",
"review": "",
"rating": "2",
"productName": "ccd",
"customrFirstName": "devi",
"customrLastName": "ss",
"address": "6th Ln, S.T.Colony, Mahalaxminagar, Rajarampuri, Kolhapur, Maharashtra 416008, India",
"contactNumber": null,
"description": "<p>ccd</p>"
},
{
"product_id": "50",
"image": "http://192.168.1.78/Linkon/site/pub/static/frontend/Linkon/default/en_US/Magento_Catalog/images/product/placeholder/image.jpg",
"shopName": "putin",
"review": "",
"rating": "2",
"productName": "car garage",
"customrFirstName": "devi",
"customrLastName": "ss",
"address": "6th Ln, S.T.Colony, Mahalaxminagar, Rajarampuri, Kolhapur, Maharashtra 416008, India",
"contactNumber": null,
"description": "<p>car garage</p>"
}
]
}
So my question is: How to create JSON model class and parse using swifty JSON?

Answer 1

I would recommend ditching SwiftyJSON in favor of the built-in Codable and JSONDecoder support in Swift 4.
For this, you simply define a struct that matches your JSON format, and decode it:
struct Data: Codable {
let status: Int
let msg: String
let products: [Product]
enum CodingKeys: String, CodingKey {
case status, msg
case products = "product_data"
}
}
struct Product: Codable {
let product_id, image, shopName, review: String
let rating, productName, customrFirstName, customrLastName: String
let address: String
let contactNumber: String?
let description: String
}
do {
let data = try JSONDecoder().decode(Data.self, from: json)
print("\(data.msg)") // e.g.
} catch {
print("\(error)")
}

You can create your data model class like below:
import UIKit
import SwiftyJSON
class ProductModels: NSObject {
var productModel:[ProductModel]?
}
public init(json:JSON) {
self.productModel = json["product_data"].dictionary
}
class ProductModel: NSObject {
var productID:String?
var image:String?
var shopName:String?
var review:String?
var rating:String?
var productName:String?
var customrFirstName:String?
var customrLastName:String?
var address:String?
var contactNumber:String?
var description:String?
public init(json:JSON) {
self.productID = json["product_id"].string
self. image = json["image"].string
self. shopName = json["shopName"].string
self. review = json["review"].string
self. rating = json["rating"].string
self. productName = json["productName"].string
self. customrFirstName = json["customrFirstName"].string
self. customrLastName = json["customrLastName"].string
self. address = json["address"].string
self. contactNumber = json["contactNumber"].string
self. description = json["description"].string
}
}
and can use this class by passing response from model who is calling api and getting this response example below: (the class where you are using this below code, you have to import SwiftyJSON)
Alamofire.request(//(your method or api call).responseJSON(completionHandler: { (response) in
switch response.result {
case .success(let value):
let productJson = JSON(value)
let productsData = ProductModels(json: productJson)
break;
}
})
