迭代Swift中的对象类属性

在 Swift中是否有一种简单的方法来迭代类的属性.

即我有一个Person类,它有3个属性：name,lastname,age.

是否有类似的东西

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

输出将是例如：

name: Bob
lastname: Max
age: 20

他们已经删除了Swift 2.0中的反射.这就是我枚举属性和值的方式.

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 after
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
