One Line Parsing JSON in Swift 4.0 With Codable or Decodle
Swift 4 includes a new way to generate and parse JSON with Swift Codable protocol.
JSON:-
{
"name" = Rahul'
"id" = 10
"collage" = RTS Collage
"code" = A190
}
Start:-
import UIKit
struct Profile: Codable {
let name: String
let id: Int
let collage: String
let code: String
Convert Item(Profile) to JSON
init?(json: [String: Any]){
guard let name = json["name" ] as? String,
let id= json["id" ] as? Int,
let collage= json["collage" ]as? String,
let code= json["code" ] as? String, else { return nil}
self.name = name
self.id = id
self.collage = collage
self.code = code
}
}
class ViewController: UIViewController {
guard let url = URL(string: "https://xxxxxxxxxx") else {return}
URLSession.shared.dataTask(with: url) { (data, response , error) in
guard let data = data else {return}
do{
let decoder = try JSONDecoder().decoder(Profile.self, from: data)
// check access data......
print(decoder.name)
} catch let err{
print("Err", err)
}
}.resume()
}
