Trying a thing.

ComputedUserDefaultsProperty.swift

class Person: NSObject {
  @objc var name: String? {
    get {
      return NSUserDefaults.standardUserDefaults().objectForKey(NSStringFromSelector(#selector(Person.name))) as? String
    }
    set(name) {
      NSUserDefaults.standardUserDefaults().setObject(name, forKey: NSStringFromSelector(#selector(Person.name)))
      NSUserDefaults.standardUserDefaults().synchronize()
    }
  }
}
