Can Swift convert a class / struct data into dictionary?

Question

For example:

class Test {
    var name: String;
    var age: Int;
    var height: Double;
    func convertToDict() -> [String: AnyObject] { ..... }
}

let

You could use Reflection and Mirror like this to make it more dynamic and ensure you do not forget a property.

struct Person {
  var name:String
  var position:Int
  var good : Bool
  var car : String

  var asDictionary : [String:Any] {
    let mirror = Mirror(reflecting: self)
    let dict = Dictionary(uniqueKeysWithValues: mirror.children.lazy.map({ (label:String?, value:Any) -> (String, Any)? in
      guard let label = label else { return nil }
      return (label, value)
    }).compactMap { $0 })
    return dict
  }
}


let p1 = Person(name: "Ryan", position: 2, good : true, car:"Ford")
print(p1.asDictionary)

["name": "Ryan", "position": 2, "good": true, "car": "Ford"]
