How do I decode this JSON Data in Swift? - ios

Question

How do I decode this JSON Data?
I've done it with the "drilling down" method where I kept calling each key and printing the value. I also tried the data model but it never worked. I probably did something wrong but I don't know what.
Thanks in advance, If you need more information, just ask, I'm fairly new to Swift and Stackoverflow.
{
"items":[
{
"id":16000014,
"name":"BO",
"starPowers":[
{
"id":23000090,
"name":"CIRCLING EAGLE"
},
{
"id":23000148,
"name":"SNARE A BEAR"
}
],
"gadgets":[
{
"id":23000263,
"name":"SUPER TOTEM"
},
{
"id":23000289,
"name":"TRIPWIRE"
}
]
},
{
"id":16000015,
"name":"PIPER",
"starPowers":[
{

},
{

"name":"SNAPPY SNIPING"
}
],
"gadgets":[

}

"paging":{
"cursors":{

}
}

Answer 1

Decoding JSON in swift is insanely easy. Just use the JSONDecoder class. Firstly, create a Codable class for your json response like this
struct Items: Codable {
let items: [Item]
let paging: Paging
}
struct Item: Codable {
let id: Int
let name: String
let starPowers, gadgets: [Gadget]
}
struct Gadget: Codable {
let id: Int
let name: String
}
struct Paging: Codable {
let cursors: Cursors
}
struct Cursors: Codable {
}
And then use it to parse your JSON like this
let decoder = JSONDecoder()
do {
let items = try decoder.decode(Items.self, from: jsonData)
print(items)
// Do something with the items here
} catch {
print(error.localizedDescription)
}

Answer 2

struct Name {
var id:Int
var name:String
}
struct Cursor {
// Your cursor model
}
struct Paging {
var cursors: Cursor
}
struct Items {
var id:Int
var name:String
var starPowers:[Name]
var gadgets:[Name]
}
struct MainModel {
var items : [Items]
var paging : Paging
}
You can decode that data using let yourData = try! JSONDecoder().decode(MainModel.self, from: jsonData) to get your desired JSON data.
