iterate over object class attributes in Swift

by

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
