iterate over object class attributes in Swift

Question

Is there a Simple way in Swift to iterate over the attributes of a class.

i.e. i have a class Person, and it has 3 attributes: name, lastname, age.

is there something like

for attribute in Person {
     println("(attribute): (attribute.value)")
}

the output would be for example:

name: Bob
lastname: Max
age: 20

They have removed reflect within Swift 2.0. This is how I am enumerating attributes and values.

class People {
    var name = ""
    var last_name = ""
    var age = 0
}

var user = People()
user.name  = "user name"
user.last_name = "user lastname"
user.age = 20

let mirrored_object = Mirror(reflecting: user)

// Swift 2
for (index, attr) in mirrored_object.children.enumerate() {
    if let property_name = attr.label as String! {
        print("Attr (index): (property_name) = (attr.value)")
    }
}

// Swift 3 and later
for (index, attr) in mirrored_object.children.enumerated() {
    if let property_name = attr.label as String! {
        print("Attr (index): (property_name) = (attr.value)")
    }
}

Output:
Attr 0: name = user name
Attr 1: last_name = user lastname
Attr 2: age = 20
