Swift 2.0 Get Mirrored Superclass Properties

Question

I need to get the properties of my class as a dictionary. For simplicity, I created a protocol which has a default implementation as follows:

protocol ListsP         


        

Answer 1

By using a protocol, you require that all the superclasses implement such a protocol to be able to use the function.

I would use a helper class, so that you can pass any object to it.

class ListsPropertiesHelper {
    static func toDictionary(mirrored_object: Mirror) -> [String: AnyObject] {
        var dict = [String: AnyObject]()
        for (_, attr) in mirrored_object.children.enumerate() {
            if let propertyName = attr.label as String! {
                dict[propertyName] = attr.value as? AnyObject
            }
        }
        if let parent = mirrored_object.superclassMirror() {
            let dict2 = toDictionary(parent)
            for (key,value) in dict2 {
                dict.updateValue(value, forKey:key)
            }
        }

        return dict
    }

    static func toDictionary(obj: AnyObject) -> [String: AnyObject] {
        let mirrored_object = Mirror(reflecting: obj)
        return self.toDictionary(mirrored_object)
    }
}

Then you can use it like

let props = ListsPropertiesHelper.toDictionary(someObject)

If you still want to be able to write

let props = someObject.toDictionary()

you can implement the protocol with the extension calling the helper class.
