NotificationUserInfoModel

Description

NotificationUserInfoModel is a simple set of convenience protocols to make passing data via NotificationCenter more Swift-like.

There are plenty of other NotificationCenter wrappers out there. NotificationUserInfoModel is not intended to compete with them. Rather, if you plan on using NotificationCenter API's as-is, then this simply helps reduce some boiler-plate code that may be error-prone.

Example

By declaring your NotificaitonUserInfoModel and creating the approprite serializer and deserializer methods, you can easily interface with NotificationCenter:

Declare Model

struct MyNoteModel {
    // add data fields here
    public var exampleString: String
}

Observer

@objc public func notificationObserver(_ note: Notification) {
    guard let myModel = MyNoteModel(note) else { return }

    /* use myModel  */
}

Emitter

let model = MyNoteModel(exampleString: "Example")
NotificationCenter.default.post(name: .ExampleNotification, object: nil, userInfo: model)

For a complete a more complete example, please see the included sample project.
