Swift 3 struct to parameter for Alamofire4 - ios

Question

Iam new in Swift and i want to convert my struct into parameter to post it with Alamofire 4.
Please excuse my bad english.
My struct is in another Class:
import Foundation
class structUser: NSObject{
var myStructUser = [person]()
struct person {
var firstName : String
var lastName : String
var age: Int
init ( firstName : String, lastName : String, age : Int) {
self.firstName = firstName
self.lastName = lastName
self.age = age
}
}
override init(){
myStructUser.append(person(firstName: "John", lastName: "Doe", age: 11))
myStructUser.append(person(firstName: "Richard", lastName: "Brauer", age : 22))
myStructUser.append(person(firstName: "Merrideth", lastName: "Lind", age : 55))
}
}
now in the Main Class I want to post the Alamofire, but how can I convert only the first name and the age from the struct?
import UIKit
class ViewController: UIViewController {
let classStructUser = structUser()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
print(classStructUser.myStructUser)
}
func postJson(){
//need format [String : Any]
for item in classStructUser.myStructUser{
// var name = classStructUser.myStructUser.name
// var age = classStructUser.myStructUser.age
}
print(classStructUser.myStructUser)
/*here i need the Json in format:
{
"name":"John",
"age":11
}
{
"name":"Richard",
"age":22
}
{
"name":"Merrideth",
"age":55
}
an so on array.count
*/
}
}

Answer 1

class structUser: NSObject{
var myStructUser = [person]()
struct person {
var firstName : String
var lastName : String
var age: Int
init ( firstName : String, lastName : String, age : Int) {
self.firstName = firstName
self.lastName = lastName
self.age = age
}
static func jsonArray(array : [person]) -> String
{
return "[" + array.map {$0.jsonRepresentation}.joined(separator: ",") + "]"
}
var jsonRepresentation : String {
return "{\"name\":\"\(firstName)\",\"age\":\"\(age)\"}"
}
}
func jsonRepresentation() -> String {
return person.jsonArray(array: myStructUser)
}
override init(){
myStructUser.append(person(firstName: "John", lastName: "Doe", age: 11))
myStructUser.append(person(firstName: "Richard", lastName: "Brauer", age : 22))
myStructUser.append(person(firstName: "Merrideth", lastName: "Lind", age : 55))
}
}
And use it like this.
let jsonString = classStructUser.myStructUser.jsonRepresentation()
