How to get particular 'json' value in swift 5? - json

Question

I want the 'success' value in json object but the problem is I'm getting whole json data I want only 'success' value to print
Here is my json`
{
response = {
success = 1;
successmsg = "Successful Connection";
};
}`
Here is my code in swift 5
#IBAction func girisButtonTap(_ sender: Any) {
var txtusername: String
var txtpassword: String
txtusername = usercodeText.text!
txtpassword = passwordText.text!
let Url = String(format: "http://10.10.10.53:8080/sahambl/rest/sahamblsrv/userlogin")
guard let serviceUrl = URL(string: Url) else { return }
let parameters: [String: Any] = [
"request": [
"xusercode" : "\(txtusername)",
"xpassword": "\(txtpassword)"
]
]
var request = URLRequest(url: serviceUrl)
request.httpMethod = "POST"
request.setValue("Application/json", forHTTPHeaderField: "Content-Type")
guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: []) else {
return
}
request.httpBody = httpBody
request.timeoutInterval = 20
let session = URLSession.shared
struct ResponseJSON: Codable {
let response: Response
}
struct Response: Codable {
let success: Int
let successmsg: String
}
session.dataTask(with: request) { (data, response, error) in
if let response = response {
print(response)
}
if let data = data {
do {
let json = try JSONDecoder().decode(ResponseJSON.self, from: data)
print(json)
let successful = json.response.success == 1
} catch {
print(error)
}
}
}.resume()
}
}
I would be grateful for any progress.

Use a model struct and Codable for parsing:
struct ResponseJSON: Codable {
let response: Response
}
struct Response: Codable {
// depending on what your JSON actually looks like, this could also be
// let success: Bool
let success: Int
let successmsg: String
}
session.dataTask(with: request) { data, response, error in
if let response = response {
print(response)
}
if let data = data {
do {
let json = try JSONDecoder().decode(ResponseJSON.self, from: data)
print(json)
// access the success property:
let successful = json.response.success == 1
// leave off the "== 1" if it's a Bool
} catch {
print(error)
}
}
}.resume()
