Iterate over object class attributes in Swift

Iterate.swift

import UIKit

struct User {
  var name = ""
  var lastName = ""
  var nickName = ""
  var age = 0
}

var user = User()
user.name  = "Sasha"
user.lastName = "Prokhorenko"
user.nickName = "minikin"
user.age = 35

let mirrored_object = Mirror(reflecting: user)

for (index, attr) in mirrored_object.children.enumerated() {
  if let propertyName = attr.label as String! {
    print("Attr \(index): \(propertyName) = \(attr.value)")
  }
}

I don't know why do you want to use these techniques nowadays. I'm sure that KeyPath is a more convenient way.
