Assign json data to labels - json

Question

I'm beginner in swift programming and I want to assign the data to labels
so I have this code below
#IBOutlet weak var Infected: WKInterfaceLabel!
#IBOutlet weak var Cured: WKInterfaceLabel!
#IBOutlet weak var Deaths: WKInterfaceLabel!
#IBOutlet weak var OmanInfected: WKInterfaceLabel!
#IBOutlet weak var OmanCured: WKInterfaceLabel!
#IBOutlet weak var OmanDeaths: WKInterfaceLabel!
func check()
{
// MARK: - CoronaData
struct CoronaData: Codable {
var countrydata: [Countrydatum]
var stat: String
}
// MARK: - Countrydatum
struct Countrydatum: Codable {
var info: Info
var totalCases, totalRecovered, totalUnresolved, totalDeaths: Int
var totalNewCasesToday, totalNewDeathsToday, totalActiveCases, totalSeriousCases: Int
var totalDangerRank: Int
enum CodingKeys: String, CodingKey {
case info
case totalCases = "total_cases"
case totalRecovered = "total_recovered"
case totalUnresolved = "total_unresolved"
case totalDeaths = "total_deaths"
case totalNewCasesToday = "total_new_cases_today"
case totalNewDeathsToday = "total_new_deaths_today"
case totalActiveCases = "total_active_cases"
case totalSeriousCases = "total_serious_cases"
case totalDangerRank = "total_danger_rank"
}
}
// MARK: - Info
struct Info: Codable {
var ourid: Int
var title, code: String
var source: String
}
if let url = URL(string: "https://api.thevirustracker.com/free-api?countryTotal=OM") {
URLSession.shared.dataTask(with: url) { data, response, error in
if let data = data {
do {
let decoder = JSONDecoder()
let gitData = try decoder.decode(Countrydatum.self, from: data)
print(gitData.totalCases as Any)
} catch let error {
print(error)
}
}
}.resume()
}
}
how can I now assign these values to the labels here (Num labels)
I know this is a stupid question to ask but forgive me for that
I just want to finish the program and learn some new things

You can download this free program to make the struct
see this example to use the struct
if let url = URL(string: "https://api.thevirustracker.com/free-api?countryTotal=OM") {
URLSession.shared.dataTask(with: url) { data, response, error in
if let data = data {
do {
let decoder = JSONDecoder()
let profile = try decoder.decode(ProfileResponse.self, from: data)
print(profile.countrydata.first)
} catch let error {
print(error)
}
}
}.resume()
}
You can change the text programmatically using the setText(:) or setAttributedText(:) method.
I replicate the request in Playground the text is different bus the way that you need to access the data is the same, country data is an array so you need to get the first element
import UIKit
import PlaygroundSupport
// MARK: - ProfileResponse
struct ProfileResponse: Codable {
var countrydata: [ProfileCountrydatum]
var stat: String
}
// MARK: - ProfileCountrydatum
struct ProfileCountrydatum: Codable {
var info: ProfileInfo
var totalCases, totalRecovered, totalUnresolved, totalDeaths: Int
var totalNewCasesToday, totalNewDeathsToday, totalActiveCases, totalSeriousCases: Int
var totalDangerRank: Int
enum CodingKeys: String, CodingKey {
case info
case totalCases = "total_cases"
case totalRecovered = "total_recovered"
case totalUnresolved = "total_unresolved"
case totalDeaths = "total_deaths"
case totalNewCasesToday = "total_new_cases_today"
case totalNewDeathsToday = "total_new_deaths_today"
case totalActiveCases = "total_active_cases"
case totalSeriousCases = "total_serious_cases"
case totalDangerRank = "total_danger_rank"
}
}
// MARK: - ProfileInfo
struct ProfileInfo: Codable {
var ourid: Int
var title, code: String
var source: String
}
class MyViewController : UIViewController {
override func loadView() {
let view = UIView()
view.backgroundColor = .white
let label = UILabel()
label.frame = CGRect(x: 150, y: 200, width: 200, height: 20)
label.text = "Hello World!"
label.textColor = .black
view.addSubview(label)
self.view = view
if let url = URL(string: "https://api.thevirustracker.com/free-api?countryTotal=OM") {
URLSession.shared.dataTask(with: url) { data, response, error in
if let data = data {
do {
let decoder = JSONDecoder()
let gitData = try decoder.decode(ProfileResponse.self, from: data)
label.text = "\(gitData.countrydata.first?.totalDeaths ?? 0)"
} catch let error {
print(error)
}
}
}.resume()
}
}
}
// Present the view controller in the Live View window
PlaygroundPage.current.liveView = MyViewController()

The countrydata is presented as an array, but the corresponding property in your model is of type String.
