Swift - Mirror - Get Property

获取实例对象对应的属性标签和值（不包括父类属性）

let mirror = Mirror.init(reflecting: person)
mirror.children.forEach { child in
    if let label = child.label {
        print("label \(label) value \(child.value)")
    }
}

如果需要获取所有属性，需要遍历父类 mirror.superclassMirror

while let mirror = mirror.superclassMirror {
    // ... 
    mirror.children
}

获取实例对象类型 mirror.displayStyle

public enum DisplayStyle : Sendable {
    case `struct`
    case `class`
    case `enum`
    case tuple
    case optional
    case collection
    case dictionary
    case set
}
