Silvery brings key-value coding to native Swift classes and structures. You can easily set and access properties just using a subscript:

var person = Person()
person["name"] = "John"

Or use the more verbose method to catch potential errors:

var person = Person()
do {
  try person.setValue("John", forKey:"name")
} catch {

Silvery brings the power of Cocoa style key-value coding to Swift.


Silvery is available through CocoaPods. To install, simply include the following lines in your podfile:

pod 'Silvery'

Be sure to import the module at the top of your .swift files:

import Silvery

Alternatively, clone this repo or download it as a zip and include the classes in your project.


To enable key-value coding for a native Swift structure or class, simply have it conform to the protocol Model:

extension Person : Model {}

You can then set and retrieve values from your model by key:

person["name"] = "John"
person["age"] = 36
if let id = person["id"] as? Int {

If you would like to handle possible errors, you can use the more verbose methods:

do {
  try person.setValue("John", forKey: "name")
  try person.setValue(36, forKey: "age")
  if let id = try person.valueForKey("id") as? Int {
} catch {

Be aware that every one of your model’s properties must conform to the protocol Property like so:

extension MyCustomType : Property {}

Implicitly unwrapped optional properties will not work properly and should be avoided:

struct User : Model {
  var id: String
  var email: String! // Will not work as expected and may result in a fatal error if set or accessed

There is another caveat when using classes. If your class inherits from a superclass with private properties, Silvery will not work as expected and may fail.
