Error trying to parse JSON using URLSession in swift - ios

Question

I'm trying to parse a test JSON from a http adress, but I get an error saying that
"No value associated with key CodingKeys(stringValue: \"name\", intValue: nil)
The JSON looks like this. It has been validated, so it should work ok:
{
"work": [
{
"name": "Jocke",
"job": "Developer",
"date": "1985-12-30T00:00:00+0000",
"best_book": {
"id": 33245,
"title": "DiscWorld",
"author": {
"id": 345,
"name": "Terry Prattchet"
}
}
},
{
"name": "Bob",
"job": "Construction worker",
"date": "2010-01-30T00:00:00+0000",
"best_book": {
"id": 375802,
"title": "Ender's Game (Ender's Saga, #1)",
"author": {
"id": 589,
"name": "Orson Scott Card"
}
}
}
]
}
The code looks like this:
struct People: Codable {
let name: String
let job: String
enum OuterKey: String, CodingKey {
case work = "work"
}
enum codingKeys: String, CodingKey {
case name = "name"
case job = "job"
}
init(decoder: Decoder) throws {
let outerContainer = try decoder.container(keyedBy: OuterKey.self)
let innerContainer = try outerContainer.nestedContainer(keyedBy: CodingKeys.self, forKey: .work)
self.name = try innerContainer.decode(String.self, forKey: .name)
self.job = try innerContainer.decode(String.self, forKey: .job)
}
}
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
guard let url = URL(string: "https://api.myjson.com/bins/fe2eo") else { return }
URLSession.shared.dataTask(with: url) { (data, response, error) in
guard let data = data else { return }
do {
let jsonDecoder = JSONDecoder()
jsonDecoder.keyDecodingStrategy = .convertFromSnakeCase
let decodedJson = try! jsonDecoder.decode([People].self, from: data)
}
}.resume()
}
}
I'm just trying to grasp the first two keys as of now, just to see if it works. But it doesn't even get past name.

Answer 1

Your api returns
[{"firstName":"Jocke","job":"developer"},{"firstName":"Anna","job":"construction"},{"firstName":"Peter","job":"pilot"}]
do {
let jsonDecoder = JSONDecoder()
let decodedJson = try jsonDecoder.decode([People].self, from: data)
}
catch {
print(error)
}
struct People: Codable {
let firstName, job: String
}

Answer 2

just try this
struct Work:Codeable {
let work:[People]
}
struct People: Codable {
let name: String
let job: String
}
do {
let jsonDecoder = JSONDecoder()
let decodedJson = try jsonDecoder.decode(Work.self, from: data)
}
catch {
print(error)
}
if you have same name as json keys you don't need to use codingkeys
